EPR Study of Gamma Irradiated N-Methyl Taurine (C3H9NO3S) and Sodium Hydrogen Sulphate Monohydrate (NaHSO3·H2O) Single Crystals

Abstract

EPR study of gamma irradiated C<inf>3</inf>H<inf>9</inf>NO<inf>3</inf>S and NaHSO<inf>3</inf>.H<inf>2</inf>O single crystals have been carried out at room temperature. There is one site for the radicals in C<inf>3</inf>H <inf>9</inf>NO<inf>3</inf>S and two magnetically distinct sites for the radicals in NaHSO<inf>3</inf>. The observed lines in the EPR spectra have been attributed to the species of SO3- and RH radicals for N-methyl taurine, and to the SO3- and OH radicals for sodium hydrogen sulfate monohydrate single crystals. The principal values of the g for SO3-, the hyperfine values of RH and OH proton splitting have been calculated and discussed. © 2010 Elsevier B.V. All rights reserved.
