I have a student that is wanting to get quantitative yields for a reaction
on polystyrene beads. She's thinking of using 13C for this, comparing
methylsilyl carbon peaks to a labelled 13C in her compound. Getting clean
quantitative 13C of the methylsilyl carbons is arduous, especially since
we do not know yet what the spin-lattice relaxation time of this carbon
is. I would appreciate your forwarding any information you might have about
carbon relaxation times.
I haven't thought real hard about this problem (we're still banging our heads
on the t1 noise problem I mentioned a week ago here), but it seems there must be
some better way(s) to measure reaction yields on beads. If any of you can
point me in the right direction for other methods (which I can pass along)
I'd appreciate it.
Thanks in advance,
