EPR investigation of irradiated strontium and zinc acetate single crystals
Article (270.8Kb)Abstract
X-ray irradiation of strontium acetate hemihydrate produces CH3C022- and not the methyl radical as
in other acetates. At higher temperatures this spectrum is replaced with two magnetically distinct
·CH2 CQ2- radicals. In the presence of the propionate. ion, further reaction proceeds at about
-30°C to yield one rotamer of one magnetically distinct CHaCHCO,- radical. The ratio of
propionate/acetate damage at room temperature is found to be 700: 1in strontium acetate, indicating
some mechanism for the delocalization of the damage. This same reaction with a substituted
propionate ion occurs in zinc acetate with a ratio of 20: 1. The coupling tensors for all species
are presented.
