Abstract
Antarctic ice and rime ice after γ-irradiation at 77 K were studied by electron spin resonance (ESR). The signal of nitrogen dioxide (NO2) was detected in both ices. The NO2 in the Antarctic ice, in particular, may be created from NO3â by reactions associated with intrinsic OH radicals. The detection limit of NO2 in solid samples was estimated to be â¼0.02 ppm with ESR. The analysis using ESR in natural ice has a potential to trace environmental NO2.
