Abstract:	Summary NMR pulse sequences for measuring coupling constants in ¹³C, ¹⁵N-labeled proteins are presented. These pulse sequences represent improvements over earlier experiments with respect to resolution and number of radiofrequency pulses. The experiments are useful for measuring J_NH, J_NCO, J_NC, J_H^N_CO and J_H^N_H. Applications to chymotrypsin inhibitor 2 (CI-2) are shown.

Keywords:	Multidimensional NMR spectroscopy ¹³C, ¹⁵N-Labeled protein Coupling constant
