Abstract

The performance of the SELINCOR sequence is greatly enhanced by using pulsed field gradients. It is shown that with this sequence, a ^13^C‐resolved COSY can be performed on a selected proton of an attached carbon atom. This experiment enables one to detect and evaluate COSY cross peaks in otherwise overcrowded regions.

New derivations of selection rules for excitation and detection of multiple quantum coherences in coupled spin-1/2 systems are presented. The selection rules apply to experiments in which the effective coupling Hamiltonian used for multiple quantum excitation is both time-reversal invariant and time
