Paramagnetic Resonance Study of NO2 in Irradiated KNO3 at 4°K

Abstract

The paramagnetic resonance spectrum of NO2 has been studied at 4°K in gamma-irradiated single crystals of KNO3. The g and hyperfine parameters are essentially the same as those for NO2 in NaNO2 but substantially different than those in KNO3 at 77°K, indicating that thermal motion at 77°K is frozen out at the lower temperature.
