| Abstract: | Hindered rotational motion of methylene groups in irradiated zinc acetate has been studied by the double modulation ESR technique. Two excited levels, at E0 = 6.7 ± 0.6 kJ mol−1 and Ej = 18.4 ± 1.0 kJ mol−1, corresponding respectively to the torsional oscillation and full Jump rotation of the methylene group, were determined. |
