Abstract : An EPR study of x-ray irradiated isobutyrate and n-butyrate doped strontium acetate hemihydrate has been made. The n-butyrate radical exhibited anistropy while the isobutyrate did not. The n-butyrate radical ion has a spectrum of 8 lines of equal intensity. The unpaired electron is on the alpha carbon and the two beta carbon hydrogens are inequivalent. The n-butyrate radical has been shown to be oriented in very nearly the same position as the propionate radical previously reported and it occupies only one of the two acetate sites. Within this site only one rotamer of the damaged ion is thermally populated. The isobutyrate ion is selectively damaged by a ratio of 300 to 1, and the ratio for n-butyrate is about 500 to 1.
