For the first time the effect of ionizing particles of different type (gamma-quanta, electrons) and neutrons upon infra-red spectra of zinc diphosphide has been studied. It was shown that the defects of phosphorus sublattice, that are the principal centers of optical activity in the infra-red (IR), are responsible for structural evolution of zinc diphosphide crystals in the process interaction with radiation of different types. Keywords: radiation, defects, exciton, annealing, spectral curve, absorption, phosphrous chain. Paper received 17.09.99; revised manuscript received 14.11.99; accepted for publication 14.03.99.
