User talk:E kwan
Welcome to Wikipedia Chem. Regarding your recent edit, I recommend that you try to revise your addition to histidine. Most of us write and rewrite our copy, so you might as well get used to the revision cycle. You are most qualified to do the revision/editing. Otherwise less specialized folks will have to deal with your writing. Your level of detail seems rather specialized don't you think? Paramagnetic contribution to chem shifts? Is one to assume that you discussing about NMR spectroscopy (as we tell students patiently, "one cannot measure an NMR") if so it was unclear because your section is so jargon-filled. Perhaps you could consider a subheader (marked with flanking ==='s on "NMR spectroscopy" of histidine. Just some suggestions.--Smokefoot (talk) 17:48, 17 February 2009 (UTC)

You probably do not want to intervene with our ongoing struggle with this particular IP vandal, but maybe I misunderstood. In general, we discourage images that show naked cations, unless no other image exists. As you will learn from talking to your teachers, Li+ does not exist except in the gas phase and the material being discussed is very covalent. But we are always open to suggestions.
I don't know anything about the IP dispute to which you're referring, but actually LiHMDS is sufficiently electronically stabilized to exist at least partially in monomeric form in many solvents. It may well have solvent ligands, but I think a picture showing the structure of an LiHMDS monomer is, in fact, informative.
Now, I give my full name, and I'm a lecturer at Harvard University and hold a Ph.D. in organic chemistry from there. Perhaps you'd care to give your name and credentials? Eugene Kwan (talk) 05:17, 28 January 2013 (UTC)
Hello Eugene, I really appreciate your contributions to the aldol reaction. It's great! Do you still have the images? If so, could you have them all in high-resolution PNG or SVG? (ChemDraw SVG usually gives errors, though.) Or are you too busy with academic stuff? Because in that case, we'll happily do it for you (https://en.wikipedia.org/wiki/Wikipedia:WikiProject_Chemistry/Image_Request). Many thanks in advance! Cheers.

You can send them via e-mail: firstname.lastname@example.org. Or if you have Outlook.com, you can upload them to your SkyDrive and share them with me (change yahoo.co.id to hotmail.com). Or you can upload them to http://www.sendspace.com and send me the link so that I can download them. Whichever is convenient to you. Cheers. Georginho (talk) 18:35, 3 November 2013 (UTC)
Hello, important ongoing discussion
Dr K …concerning the future direction of the Natural Products article, please see the "Class" section in that article, and skim remaining. Article is in a current sorry state, and it is apparently avoided for its current structure and constraints. See developing discussion at . Perhaps you have a view to express. You can see my User page, hidden though it is—un-gray by clicking on Edit tab—to see who I am. Le Prof Leprof 7272 (talk) 18:30, 3 June 2014 (UTC)
