Wide-line nuclear magnetic resonance studies of methylammonium chloride, bromide, and iodide and their partially deuterated analogues show that second-moment and line-width transitions occur which can be interpreted as due to molecular reorientation about the C—N axes. In the bromide and iodide salts this motion persists below 77 °K.
