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!
