title: Gamma-irradiated calcium succinate monohydrate single crystal investigation with EPR technique.
abstract: In this study, EPR investigation of gamma-irradiated calcium succinate monohydrate [CaC(4)H(4)O(4)·H(2)O] single crystal has been carried out at room temperature. The compound crystallizes in monoclinic symmetry with the unit-cell dimensions: a=11.952(2)Å, b=9.691(2)Å, c=11.606(2)Å, β=108.81(1)°. The observed lines in the EPR spectra reveal the formation of C˙H(α)CH(β1)H(β2) radical after irradiating [CaC(4)H(4)O(4)·H(2)O] single crystal. The angular variations of EPR spectra have shown that the radical type has only one site in three perpendicular planes. The principal g and a values and direction cosines of C˙H(α)CH(β1)H(β2) radical have been determined.
