dc.description.abstractAn EPR study of copper halide tetrazole complexes and x-irradiated strontium acetate hemihydrate has been made. The powder spectra of some of the tetrazole complexes exhibited temperature dependent narrowing and broadening. The one-electron population of the copper d orbital involved in bonding to 2-methy l-5-amino tetrazole has been found to be 0.56 and 0.47, respectively for the chloride and bromide complexes. The g value for these two complexes are consistent with the proposed planar polymeric structure for 2-substituted tetrazole- copper complexes. The species present in single crystals of strontium acetate hemihydrate irradiated and observed at liquid nitrogen temperature to -100 C has a spectrum of four lines of 1:3:3:1 intensity ratio and aCH3 = 11.0 gauss. Temperature dependent exchange behavior of the spectrum for this species is observed and attributed to a rotating methyl group which was found to have 6H# = 3.0 + 0.3 kca l and 6S# = 6.0 + 0.3 cal/mole deg for internal rotation. The species present at room temperature has an eight line spectrum consisting of two 1:3:3:1 intensity ratio patterns with a CH3 = 25.2 and aH - 21.3 gauss. Molecular orbital calculations using the CNDO approximation were performed and possible fragments responsible for these spectra are suggested. 25.2 and a = 2 1 . 3 gaus s .
