title: Molecular dynamics in solid pregnenolone studied by 1H spin-lattice relaxation.
abstract: Spin-lattice relaxation times T1 in solid pregnenolone have been studied over a wide range of temperatures, from 77 up to 417 K. The dynamic processes arising from C3 motion of the three methyl substituents are separated, and their activation parameters are determined.
