Molecular dynamics and phase transitions in solid 2-methyl-2-propanethiol studied by ¹H N.M.R. relaxation

Abstract

Spin-lattice relaxation times T 1 and T 1ρ for protons in solid 2-methyl-2-propanethiol are presented. The relaxation measurements corroborate the existence of three solid-solid transitions and give some insight into their nature. The motions occurring in the respective phase modifications are discussed and their activation parameters derived.
