Molecular motion and barriers in N2H5Cl and N2H5Br studied by inelastic neutron scattering and proton magnetic resonance spin lattice relaxation

Abstract

Molecular ion motion in the salts N₂H₅Cl Br has been studied by inelastic neutron scattering and proton magnetic resonance spin-lattice relaxation times. Activation energies and approxiamte simple harmonic barriers for rotation of the —NH⁺₃ group in each salt have been determined. Some conclusions have been drawn about the nature of the external barriers restricting motion of both the —NH⁺₃ and the —NH₂groups.
