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.
