The chemical shift, spin-lattice relaxation time, and intensity of nuclear magnetic resonance line were measured for ammonium chloride, bromide and iodide in various phases. It was found that the reorientational motion of ammonium ion is the origin of time dependent interaction necessary to relax the nuclear spin orientation. The deformation of the halogen ion core, arising from the interaction with alkali ions, is discussed in connection with the chemical shift and spin-lattice relaxation time. In ordered phase, T_1 in the chloride became much longer than that in phase II, while in the bromide electric quadrupole splitting of NMR line appeared, and the ordering parameter was estimated. From the result of the intensity measurements, the effect of crystal imperfection upon NMR is discussed.
