摘要：
The applicability of HECADE approach to the measurement of C-13, 1 long-range coupling constants, which was difficult to achieve by other methods, is demonstrated. The coupling magnitudes obtained allow the qualitative characterization of rotational degrees of freedom in all isomers of the beta-sulfonylenamines studied in terms of the prevailing conformation contribution to conformational averaging.
