I have a student that is pursuing some very precise chemical shift
measurements in support of theoretical work. He asked me about
publications discussing the shift in absolute frequency that occurs
with TMS with temperature, solvent, and/or concentration. I
would appreciate any feedback you might provide in this area.
Thanks,
