Proton spin-lattice relaxation rates (Rl values) have been measured, at 400 MHz, for a number of 2-methyland 2,2-dimethyl-substituted 4,6-diamino-l-aryl-l,2-dihydro-s-~es. These compounds have high barriers to internal rotation about the aryl C-N bond, and exist in solution as mixtures of enantiomer
