Molecular Motions in Several Solids Studied by Nuclear Magnetic Relaxation in the Rotating Frame

Abstract
Rotating frame nuclear magnetic relaxation times have been measured as a function of temperature from 117 to 290°K for perfluorocyclohexane, cyclohexane, 2,2‐dichloropropane, neopentane, and tetramethylammonium iodide. The data are interpreted in terms of molecular rotation and diffusion in the solid state.
