I've made a new image, which seems to look ok. I've replaced the .png image on the Bupropion page, I take it this is what it was intended for? File:Bupropion skeletal.svgDavid-i98 (talk) 00:46, 3 January 2008 (UTC)
Got an image of a couple types. I don't have anything to pack them with right now, but I'll try to grab another picture of one when I do. File:Chem drying tubes.jpgBfesser 03:49, 25 February 2007 (UTC)
That's great! Thanks! --Rifleman 82 06:03, 25 February 2007 (UTC)
For alkane article, please can 2-methyl-butane, with the numbering (1-4) put on the butane chain, thanks -- Quantockgoblin 07:45, 6 February 2007 (UTC)
For alkane article please can I have the all possible C4-alkane isomers (i.e. n-butane, isobutane, cyclobutane and methylcyclopropane as a composite image. Also do anyone think it is reasonable to include the cyclobutane with a bridging carbon-carbon bond (i.e. like two triangles back to back) - does it even exist as an intermediate? Currently there is an incomplete list of all possible C5-isomers on the alkane page. I'd like to replace that image with the one requested. Also, we are typing to make alkane a featured article, it would be great if you can make the iamge nice on the eye. -- Quantockgoblin 00:40, 6 February 2007 (UTC)
- done (at low-ish resolution) - I'm sure someone can do it at higher and with svg?
Do you mean SVG for the skeletal formulae or the ball-and-stick models? The latter usually look better as hi-res PNG. Fvasconcellos 17:21, 11 February 2007 (UTC)
Actually before you kindly do anything, I've just thought, are cyclic alkanes strictly isomer of straight chain alkanes e.g. hexane C6H14 and cyclohexane C6H12 have different chemical formula! If they are not isomers (which now I suspect) then maybe I don't need the image as it is factually incorrect. The 'isomers' I have drawn are just C4-analogs!?! --Quantockgoblin 21:45, 11 February 2007 (UTC)
Cycloalkanes are isomeric with alkenes - they have the general formula CnH2n. What you want are all the possible isomers with formula C4H10.Ben 21:48, 11 February 2007 (UTC)
LOL. Thank you for validating—do we need a reference for that? :D Fvasconcellos 22:13, 11 February 2007 (UTC)
Ok, I've decide that I can still use the image as shown right with a correct lable. So with reference to Fvasconcellos original question, ball and stick please! -- Quantockgoblin 08:10, 12 February 2007 (UTC)
Will do. Done—how's this to the left? Is the file too big, and is the filename OK? I couldn't think of what to call it :) Fvasconcellos 12:27, 12 February 2007 (UTC)
Looks very good to me - already replaced old image on alkanes page, thanks! -- Quantockgoblin 23:51, 12 February 2007 (UTC)
The section Benzopyrene#Interaction with DNA just got a Template:Tl, and I can see why, the text is heavily invested with chemical formulae, which makes the section unreadable for many people. I think that an reaction scheme (and a rewrite of that section) would clarify a lot, there (I can help with the rewrite, if you want). --Dirk BeetstraTC 10:57, 17 December 2006 (UTC)
Could someone please replace Image:Con polymer.png with a version that has licensing and source information? I would tag it with Template:Tls and Template:Tls, but I doubt whether this image can be deleted (due to technical concerns). Thanks. MER-C 08:17, 18 February 2007 (UTC) (copied from wikipedia talk:wikiproject chemistry Dirk BeetstraTC 09:27, 18 February 2007 (UTC)).
Uracil seems to have a problem, a user left the note "This scheme and the sentence are wrong : a tautomeric equilibrium is between two different molecular forms (as shown, with proton(s) transfered from one site to another), but a double arrow must be used. Resonance structures show the electrons (usually pi electrons), for an unique molecular structure, localized in different parts of the molecule. This is symbolized by the arrow with two heads as on this drawing. The resonance theory helps understanding the stability and reactivity of molecules. The two molecules shown have each their own resonance structures.". --Dirk BeetstraTC 17:08, 20 February 2008 (UTC)
I added in the scheme from iodomethane, with a little explanation. Maybe you also want a schematic of a biochemical methylation, too? That's out of my field...Walkerma 16:30, 20 March 2007 (UTC)
Photo of a stable carbene. This is a bit of a wild request, but if people are still in the habit of subliming stable carbenes, perhaps they could take a photo and upload it. A nice way to sublime these carbenes (when free from metals) is to place a tight fitting rubber filtration cone (the sort used for getting a good seal when using a Buchner funnel) half way up the outside of a schlenk tube and fill it with dry-ice acetone and gently heat the crude solid carbene in the bottom of the schlenk tube with warm water whilst applying a vacuum. The carbene sublimes as a nice white band, perfect for a photo. I would do it myself, but I'm no longer in the lab. Quantockgoblin 18:00, 14 November 2006 (UTC)
A nice picture for Template:Tl (I would like to use this template outside the infoboxes to request images on chemistry pages where a picture would e.g. improve the explanation or replace wrong images with this template). Feel free to make something beautiful! --Dirk BeetstraTC 15:23, 4 March 2007 (UTC)
The image at that page when resized looks not very nice. Maybe our diagram/svg experts - User:Quantockgoblin or User:Fvasconcellos or anyone else would be interested? --Rifleman 82 16:37, 16 April 2007 (UTC)
I can take this on, if you'll wait until tomorrow :) Fvasconcellos (t·c) 16:45, 16 April 2007 (UTC)
That's great! No hurry! --Rifleman 82 17:18, 16 April 2007 (UTC)
How's this? I adapted the one we have right now; unfortunately the file came out quite large (520 KB). Fvasconcellos (t·c) 14:30, 17 April 2007 (UTC)
Copper aspirinate - space filling model of crystalline state, maybe? I'll take care of the reaction mechanisms Bfesser 03:28, 25 February 2007 (UTC)
Xray structure is reported in Script error: No such module "CS1 identifiers". but I don't have access to that one or know where to find its coords online. Could probably fake it from the DMSO adduct Xray in Script error: No such module "CS1 identifiers".? Probably better to have just (ball-and-)stick instead of real VdW space-filling since it's such a clustery thing. DMacks 08:26, 17 April 2007 (UTC)
Okay, I added a stick structure. Good enough, or do we need more/different format? DMacks 17:58, 17 April 2007 (UTC)
Endo-exo isomerism done by Rifleman, others done by me. I'd appreciate it if you could check them for accuracy. Fvasconcellos (t·c) 19:04, 20 August 2008 (UTC)

I would like to request for the Wikipedia:Chemistry Collaboration of the Month article solubility some images relevant to this page, obvious things as solids being dissolved or an image of two immiscible liquids on top of each other. I lack a laboratory and a camera! so help much appreciated.... V8rik 20:20, 22 January 2007 (UTC)
An example of a real-life particle in a box system. Say, a photograph of an NaCl cube after being heated in sodium vapour. --HappyCamper 18:32, 24 April 2007 (UTC)
double oblique stopcock; a photo of one of these please - i.e. the type of tap used in a vacuum-gas manifold (i.e. a glass tap with 2 separate parallel 'channels/lines' that run diagonal to the axis of the tap). -- Quantockgoblin 00:05, 13 February 2007 (UTC)
A graphic and/or a photograph of a (e.g. THF) still, used for distilling off solvents from a pot containing a desiccant/oxygen scavenger. The still I have in mind, from the bottom:
pot with a second neck for adding sodium and more solvent
pressure-equalizing dropping funnel modified with a neck (replace stopper with septum against N2 flow to draw off purified solvent)
Graham condenser to cool pure solvent vapors, with mouth of stopper connected to a N2 line connected to a bubbler. --Rifleman 82 (talk) 06:09, 18 July 2008 (UTC)

Wanting to make a infobox for chemistry topics which looks similar to the Cuisine feel of infobox; would require a picture or diagram of something which personifies chemistry in both practical and theoretical instances. So, something like a beaker, Erlenmeyer flask, chemical formulae or notable chemist, just give a little more "oomph" to the wikipedia chemistry articles. JCraw 13:22, 27 November 2006 (UTC)
Suggestions:
A mini table of elements? Maybe does not have enough "oomph", but would at least be instantly recognizable? -- Quantockgoblin 16:47, 27 November 2006 (UTC)
I prefer the periodic table. Emphasizing the hazards of chemistry sends a bad message, in my opinion. --Ed (Edgar181) 13:25, 29 November 2006 (UTC)
Ed, I think you are right - I was looking for something with a bit more colour/oomph - (more arrrghh than oomph it would seem!!) --Quantockgoblin 13:54, 29 November 2006 (UTC)
What if we made a collage of materials? --HappyCamper 14:46, 8 December 2006 (UTC)
or maybe a bit chemistry apparatus "as seen on TV" e.g. (although I would need all the bits to be in the wrong order and some dry ice in there somewhere too!!):
The triene designation refers to the signature ultraviolet spectrum due to three conjugated double bonds. The subscript denotes the total number of double bonds - four when derived from arachidonate.
Could anybody supply that UV spectra? David.Throop 17:03, 15 January 2007 (UTC)
Can anyone get a 13C NMR spectrum of ethanol which clearly show the 13C satellite peaks. I want to use this in the Isotopomers article to show the difference between Isotopomers and isotopologues -- Quantockgoblin 13:04, 18 April 2007 (UTC)
Maybe contact the people behind [2] and see if they will donate theirs? DMacks 13:51, 18 April 2007 (UTC)
I took a hand at drawing the various crystal field splittings using Dia but they look ugly. I was wondering if anyone would be willing to draw the diagrams for

I think DMSO is often misrepresented as planner (i.e. sp2 at S). The S is tetrahedral like oxygen (SP3). The nice images on the DMSO pretty much give this impression, as does the image on the D-DMSO page. I would like someone to fix the images so they are more representative of the real sp3 S-center -- thanks Quantockgoblin 12:55, 18 April 2007 (UTC)
I saw an edit to Capecitabine, where is claimed that the image is wrong, it should be a pentyl group, not a butyl group, can someone into that, cheers! --Dirk BeetstraTC 11:18, 8 August 2007 (UTC)
