States of Solid Methane as Inferred from Nuclear Magnetic Resonance

Abstract

As there are different points of view concerning the molecular dynamical states in solid methane, especially concerning the $\lambda$-transition at 20.42°K, we have investigated the manner in which the new method of nuclear magnetic resonance throws light on the problem. Both the one-parameter theory and the method of perturbation were applied to the analysis of the proton resonance data given by Thomas, Alpert, and Torrey.
