摘要：

Molecular modeling by molecular mechanics (MM2) calculations were used to predict conformational preferences of cyclic N-nitrosamines. The results were compared with H-1 NMR data. The observed geminal coupling constants (2)J were considerably stronger for syn than for anti alpha-methylene protons and thus appear to be very useful for configurational predictions. The long-range (4)J couplings across the nitrogen atom were observed directly from the 1D spectre.
