✦ Synopsis

Abstract

Recent work has shown that broadband heteronuclear Hartmann—Hahn coherence transfer is an efficient alternative to pulsed coherence transfer methods. A new technique for heteronuclear long‐range correlation between ^13^C and protons, making use of proton detection and an extended mixing period, is described, which can have sensitivity and resolution advantages over current techniques. Efficient regiospecific correlation is shown in a model system, menthol, and the use of a modulated spin‐‐echo for the simultaneous determination of one‐bond and long‐range correlations is demonstrated.
