Thought so...<br /><br />Our group has once received empty ampules of CD3OD. Doing NMR with a gas as a solvent would be weird. I wonder if that's possible. If it is, I chose D2! Anyway, more than likely it's all escaped, which brings me to my point, unidentifyable solvent is better than no solvent at all :)<br /><br />-BeakerBunsen and Beakerhttps://www.blogger.com/profile/05289360253466908461noreply@blogger.comtag:blogger.com,1999:blog-4387100009341358284.post-37045463271724684762006-12-12T18:21:00.000+01:002006-12-12T18:21:00.000+01:00My guess: the colored tops were more indelible tha...My guess: the colored tops were more indelible than a label. How many times have you seen a half-torn-off illegible sticker on a vial in the lab? And it's solvent, so getting Sharpie ink off is no trouble.<br />Just my $.02...Ψ*Ψhttps://www.blogger.com/profile/09667196069550812481noreply@blogger.comtag:blogger.com,1999:blog-4387100009341358284.post-12455099253773729102006-12-12T12:12:00.000+01:002006-12-12T12:12:00.000+01:00Our vials, your old ones, are a little different. ...Our vials, your old ones, are a little different. The orange top (labeled red) is dichlormethane d2 and the pink top (labelled ???) is acetone d6. Personally, I still ignore the chart and enjoy playing the random solvent game.Stevehttps://www.blogger.com/profile/15376217760783701841noreply@blogger.comtag:blogger.com,1999:blog-4387100009341358284.post-21628025552609693172006-12-12T10:39:00.000+01:002006-12-12T10:39:00.000+01:00And now the obvious question.

NMR wasn't a big enough mystery, so they wanted to make it a little bit more difficult?Anonymousnoreply@blogger.com
