摘要: The electron spin resonance spectra of γ‐ray‐irradiated glassy and polycrystalline phosphorus pentoxide alkali phosphates with molar ratios to oxide ranging from 3.33 0.625 have been observed at 10 35 Gcps 300° 78°K. Well‐resolved hyperfine doublets were in each glass or powder. Additional resonances also present all the specimens but these are not discussed. widths shapes independent temperature only small alterations component a doublet found as function frequency. One set has discussed elsewhere is considered. Those which attributed an trapped nonbridging oxygen vacancy. Interaction nearest‐neighbor 31P nucleus (100% natural abundance, I = 12) produces structure. These exhibited isotropic interactions 1880 449...
