Abstract
Proton spin-lattice relaxation timesT 1 in 17α hydroxy- and 21 hydroxy-progesterones have been performed in the temperature range from 100 to 400 K at the frequencies of 30 and 90 MHz. The dynamic processes involving the methyl group reorientation about the threefold symmetry axis of the C−C bond are separated, and their activation parameters are determined.
