This question is along the same lines as the "how many elements have you worked with" post below!   Last night some of the "pit VIPErs" (our pet name for those of us who got this site started) were discussing bizarre and interesting NMR experiments.  We thought it would be fun to compare the types of weird nuclei, pulse techniques, etc.  that the VIPEr users have done either in research or in a laboratory class.   I'll start out the conversation with a couple of my weirder ones:  I've done both 207Pb and 119Sn  spectra as well as 2D TOCSY of paramagnetic species.  Anyone else?  Who knows, maybe it will give someone an idea!

195Pt is the weirdest nucleus I've found by NMR. I've done some 1H/195Pt 2D NMRs. Nothing real fancy.

I have done chalcogen NMR (pronounced like chalk, NOT like Kale).  77Se and 125Te of E=Mo(=NR)(NRR')2 complexes.  And lots and lots of 2H NMR.  Those experiments were back in grad school days.  Now, I do a lot of 31P in the teaching lab, but just plain old boring 1H for my research.

I thought I would change this a little.  What NMR have you obtained with the greatest number of different active NMR nuclei appearing.

For example:  I took a C13NMR of W(CO)3dppe(F)(CCH2Ph).  Active Nuclei: H1, W183, P31, C13, F19

All those nuclei show up in the C13NMR of the carbonyls.

Wow, that's great.  And, you're going to scan in that NMR and post it as a problem set question so I can use it on my final exam, right?

Adam,

I will have to locate  the spectrum first.  This goes back to my graduate days; so, hopefully it is in my thesis

While I'm someone who hasn't done lots of NMR, I made a couple of Pt compounds as a grad student and took 195Pt NMR of them.  

I'm looking forward to learning how to do some NMR with oligonucletides while I'm on sabbatical next year.

Dear Kurt,

I think you win by a lot. The best I can do to compete is an asymmetric molybdenum dimer I made once with six neopentoxide ligands. Each ligand gave an AB pattern, due to the diastereotopic protons on the carbon next to the metal. I could actually see all six.

Joanne,

I am amazed you were able to resolve all those AB patterns.  Must have been a big magnet.

I wanted to bump this thread up, and also if anyone has interesting inorganic compound spectra, I think you should make an LO on spectra interpretations! 

I haven't done anything fancy recently, just 1H, 13C, 19F, 31P, and 11B pretty routinely.
