Pulsed Gradient Spin-Echo (PGSE) Diffusion and ~1H,~(19)F Heteronuclear Overhauser Spectroscopy (HOESY) NMR Methods in Inorganic and Organometallic Chemistry:Something Old and Something New

摘要

The determination of relative molecular size in solution remains a subject of considerable interest to the chemistry community.This is especially true with respect to the formation of polymers,biopoly-mers,polynuclear materials,and otherwise aggregated materials.Apart from mass spectroscopic methods,diffusion methods have found increasing favor in this area.
