Abstract
A three-dimensional experiment is described in which NMR signals are s eparated according to their proton chemical shift, C-13 chemical shift , and diffusion coefficient. The sequence is built up from a stimulate d 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.
