Özet

In this study, EPR investigation of gamma-irradiated calcium succinate monohydrate [CaC(4)H(4)O(4)center dot 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) angstrom. b = 9.691(2)angstrom, c = 11.606(2)angstrom, beta = 108.81(1)degrees. The observed lines in the EPR spectra reveal the formation of (C)over dotH(alpha)CH(beta 1)H(beta 2) radical after irradiating [CaC(4)H(4)O(4)center dot 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)over dotH(alpha)CH(beta 1)H(beta 2) radical have been determined. (C) 2011 Elsevier B.V. All rights reserved.
