A three-dimensional DOSY-HMQC experiment for the high-resolution analysis of complex mixtures
A three-dimensional experiment is described in which NMR signals are separated according to their proton chemical shift, 13C chemical shift, and diffusion coefficient. The sequence is built up from a stimulated echo sequence with bipolar field gradient pulses and a conventional decoupled HMQC sequence. Results are presented for a model mixture of quinine, camphene, and geraniol in deuteriomethanol. Copyright 1998 Academic Press.
