## Abstract Molecular modeling by molecular mechanics (MM2) calculations were used to predict conformational preferences of cyclic __N__‐nitrosamines. The results were compared with ^1^H NMR data. The observed geminal coupling constants ^2^__J__ were considerably stronger for __syn__ than for __ant
