摘要

A method of 2-dimensional nuclear magnetic resonance (2D-NMR) correlation spectroscopy, comprises a pulse sequence with the following steps: excitation of double quantum coherence; immediate reconversion to single transition single quantum coherence; evolution of the set of single transitions; mixing with zero quantum mixing Hamiltonian; and signal detection. The method can achieve an improved sensitivity, has a transition selectivity and suppresses diagonal peaks.
