The influence of the size effect of the crystallites in powders on the form and width of spectral lines, on the spin-spin and spin-lattice relaxation parameters of the nuclear quadrupole resonance (NQR) of 14N nuclei in sodium nitrite was studied. It was established that a decrease of the average crystallite size produces the widening of the NQR lines and the shortening of the relaxation times in the direct method of NQR detection. It was supposed that these are the results of the spin-spin diffusion process. A multi-exponential inversion of the decays of the longitudinal and transverse components of the nuclear magnetization was used to obtain the distribution of relaxation times.
