摘要

The results of an experimental study of phase transitions in molecular crystal of paradichlorobenzene by the nuclear quadrupole resonance relaxometry method with inversion of the Laplace transform are described in the article. The distributions of relaxation times T (1), T (1 rho) and for alpha- and beta-phases of p-C6H4Cl2 are measured. It is determined, that spin-spin relaxation times have unimodal distributions for alpha- and beta-phases, and spin-lattice relaxation times, including in rotating system of coordinates-multimodal distributions. It has been shown that spontaneous beta -> alpha phase transition does not arise in the porous material preliminary impregnated with the fused sample and the beta-phase is steadily retained.
