Abstract
The effect of energetic γ-radiation on 1H NMR, electronic absorption, ESR spectra, differential thermal analysis (DTA) and solid state dc electrical conductivity of the ligand N-phenyl-2-(2-(phenylamino)acetyl)hydrazine carbothioamide (H2L) and its copper(II) complexes; Cu(HL)(OAc)H2O, Cu(HL)BrH2O and Cu(H2L)2(NO3)2⋅3H2O before and after γ-irradiation (hereafter referred to as (B), (B 1 ), (B 2 ), (B 3 ) and (A), (A 1 ), (A 2 ), (A 3 ), respectively) has been studied. Electronic spectral bands of the complexes after irradiation exhibited some better resolved shapes with a remarkably higher absorbance, ESR spectrum of complex Cu(HL)BrH2O (B 2 ) before irradiation showed isotropic spectrum with g iso = 2.075 however, after irradiation (A 2 ) displayed axial ESR spectrum with g ∥ > g ⊥ > 2.0023 and d (x2−y2) ground state. DTA of the compounds reveals that γ-irradiation induced generation of new peaks as well as changes in the peak intensities. Solid state dc electrical conductivity for complexes was investigated before and after γ-irradiation. Complexes were found to be semiconductors, the activation energies (E a) were calculated for the complexes by using the Arrhenius plot.
