内容記述(抄録等)
ESR spectra of the radicals produced in polycrystal and single crystal of BF_3 under γ-irradiation at 77 K were investigated. From analyses of these spectra, the radicals were identified as BF_3- and BF_2 radicals, respectively. ESR parameters of these radicals were the very same with those reported in literatures. Furthermore, the analyses showed that an interesting long-range interaction of the BF_2 radical with the nearest neighboring two molecules is involved and the distance between the BF_2 radical and the nearest neighboring fluorine atom is ca. 2.8 Å.
