Abstract

It is demonstrated that the Müller and Bolton type of multiple‐quantum heteronuclear shift correlation is a promising tool for stereosequence assignments of polymers. Slight modification of the basic MQ pulse sequence results in a 2–3‐fold gain in sensitivity compared with the conventional single‐quantum spectra while retaining the one‐quantum frequency scale in the F~1~ dimension.
