ESR of gamma irradiated (NH4)(2)C2O4 center dot H2O and K2C2O4 center dot H2O single crystals

Abstract

The gamma irradiated samples of both vacuumed powders and single crystals of (NH4)(2)C2O4.H2O and K2C2O4.H2O have been investigated by ESR method. The spectra for both these crystals were attributed to RCHOH and CO2- radical, respectively, but CO2- radical was observed only in the powders in vacuum. Furthermore, A and g values also were found for these samples.
