Abstract:

A decrease of one to six gauss depending on magnetic field orientation in the coupling constants of the CH2CO2- radical formed in X-irradiated zinc acetate dihydrate has been observed over a temperature range of about -60C to 30C. Calculations of dipolar and Fermi contact interaction based on a model of internal rotation of the methylene group about the C-C bond have shown a small coupling constant decrease on the order of 0.19 gauss over a temperature range of -150C to 90C. The major effect has been shown to be due to a spin relaxation mechanism. The effect was calculated using Monte Carlo techniques, the results of which were confirmed by experimental data. Author
