Abstract
A simple, artifact-free, one dimensional NMR method for correlating 1H and 13C NMR resonances, termed selective heteronuclear correlation (SHECOR) is described. The method employs a selective 1H pulse followed by a 13C gated spin echo sequence, and the resulting 13C signal is observed in the presence of 1H broadband decoupling. When the frequency of the selective 1H pulse coincides with a 1H NMR satellite from a 13CH n group, an intensity-enhanced decoupled 13C NMR signal is obtained. In addition to 13C 1H correlation, partial multiplicity assignment is achieved, allowing differentiation between resonances from CH 2 and either CH or CH 3 groups.
