Abstract
Analysis of the radicals created in the TGS: Fe3+ crystal after UV-irr adiation in the temperature 4.2 K using EPR technique are presented. B efore UV-irradiation the low temperature (4.2 K) EPR spectra of TGS: F e3+ due to Fe3+ ion is observed. After irradiation Fe3+ spectrum vanis hes and new spectrum due to NH2+ radicals is observed. A model, based on the charge transfer from the ligands (NH2CH2COO)(2) onto the centra l ion Fe3+, is presented.
