The analysis of spin-lattice relaxation in nuclear quadrupole resonance (NQR) of spin -5/2 reported by Okubo and Igarashi (Z. Naturforsch. A. 56 (2001) 777) is extended to take account of the distribution of the initial non equilibrium populations created by a resonant radio-frequency pulse in powder. The proposed theory is applicable to axially symmetric electric field gradient tensor and is examined for spin-lattice relaxation of (127I) NQR in polycrystalline pyridine iodine monochloride measured at 469 MHz at 77 K.
