Abstract

The proton spin-lattice relaxation time $T_1$ and second moment $M_2$ have been measured in dihydrazinium sulfate $(N_2H_5)_2SO_4$ in the temp. range 77-300 K to understand the nature of mol. motions. Two $T_1$ min. and an $M_2$ transition have been obsd. The obsd. $T_1$ min. are explained in terms of the reorientation of two inequiv. $NH_3$ groups. The second moment behavior has been interpreted in terms of NH3/NH2 motions. The activation energies of the inequiv. $NH_3$ groups are 28.0 and $28.5 kJ mol^{-1}.$
