AbstractÐSelective and double-selective J-HMBC 2D methods were developed and employed to determine the coupling constants of harman (1). The 1 H± 13 C and 1 H± 15 N long-range coupling constants could be accurately determined without interference from the 1 H± 1 H Jmodulation effect. We also applied
