Abstract : An 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-methyl-5-amino tetrazole has been found to be 0.56 and 0.47, respectively for the chloride and bromide complexes. The g values 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 -100C has a spectrum of four lines of 1:3:3:1 intensity ratio and a CH3= 11.0 gauss. Molecular orbital calculations using the CNDO approximation were performed and possible fragments responsible for these spectra are suggested. (Author)
