Abstract:Hyperfine and g-tensors for chlorine monoxide, dioxide, and trioxide areThe identity of radicals trapped in y-irradiated perchlorates presented. and chlorates and detected by electron-spin resonance is discussed.
“…The available spectral parameters of Ago, Ag' ' (17), and the chlorine oxyradicals (18,19) eliminate them as possible species responsible for the observed spectra. Since cycloolefins and some of their adducts yield cycloalkenyl radicals when subjected to ionizing radiation (20,21), it is probable that the corresponding Ag'cycloalkenyl radicals are produced upon y-irradiation of the silver~ycloalkene complexes (eq.…”
Paramagnetic species have been detected in y-irradiated polycrystalline silver perchlorate -cycloalkene complexes at room temperature and identified as Ag+cycloalkenyl radicals, with spin density on Ag decreasing from 4.6 to 1.5% with increasing size of the cycloalkenyl ring. The extent of the spin density on Ag increases with the stability of the parent complexes.

“…Tetrahedral radicals such as SO4-and P042-have been detected (19), and the principal g-values for SO4-h persulfate are 2.033,2.008,2.004 (average 2.0149). Such radicals are expected to possess a .…”
Single crystals of Na2S203.5H20 were irradiated and examined, a t room temperature, with an e.s.r. spectrometer. Two radicals are present: the species present in highest concentration is the other species has not yet been identified.
“…As may be seen, two groups of lines appear: sample in the resonant cavity. It can be attributed to ionic SO-defects established to appear in irradiated potassium persulfate (8).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
