The e.s.r. spectrum of the (CH3)2ĊOH radical showed a drastic temperature dependence of linewidth in the range −196 to −100 °C, this being particularly pronounced for the M1 = ±2 lines. Possible mechanisms are discussed in terms of restricted rotation of the methyl groups and of the OH groups.

Abstract NaNO3, Sr(NO3)2, BaS, and MgC2O4·2 H2O powders have been gamma-irradiated at room temperature and their electron spin resonance spectra examined for paramagnetic species. The species identified were NO3 and NO2 radicals in the nitrates, SO2- and S in BaS, and H2C2O4- in magnesium oxalate. Theoretical predictions agree with these assignments.
