Abstract
The applicability of HECADE approach to the measurement of C-13, 1 long-ran ge coupling constants, which was difficult to achieve by other methods, is demonstrated. The coupling magnitudes obtained allow the qualitative charac terization of rotational degrees of freedom in all isomers of the beta-sulf onylenamines studied in terms of the prevailing conformation contribution t o conformational averaging.
