A NMR DEPT-HMQC (distortionless enhancement by polarization transfer-heteronuclear multiple quantum coherence) pulse sequence is presented in which the discrimination of different multiplicities is not identical to the normal DEPT transfer. Expressions for the CH, CH2, and CH3 terms present at the end of the DEPT sequence, meaning the beginning of the evolution period, are given in terms of b, the flip angle of the 3rd pulse. Illustrative spectra obtained by applying the pulse sequence are presented.
