Broad-line nuclear magnetic resonance investigation of molecular motion in solid trimethylamine–halogen complexes

Broad-line nuclear magnetic resonance studies of the charge-transfer complexes of trimethylamine (NMe3) with iodine, bromine, and iodine monochloride indicate the presence of motion in the solid state. Trimethylamine itself was studied for purposes of comparison. The nature of the motional transitions for each species has been determined, and activation energies derived.
