I am going to start doing some NMR on my particles (ZnS ~ 3nm) to see if there is chemically bound dyes or other molecules attached. anyone have any pointers? one thing i was worried about is generating a surface plasmon, or other heat-generating phenomena, that would explode my NMR tube.

what should i expect that's different from a regular NMR? any crazy baselines or something? thanks in advance.

well the NMR worked fine, although my sample wasn't that concentrated. nothing exploded.

i guess DOSY is a new pulse sequence that may be of use to you if you start doing NMR on particles with organic compounds attached.
