The deuterium concentration D% of the radiation products was determined by GC-MPES method
the probability of bondbreaking of C—P bond was 0.013
and of O—C bond was 0.987. The ESR spectra measured after γ-irradiation of DPPP samples at ambient temperature dominated by that for cyclohexadienyl-type radicals
while the spectra of low-temperature (77 K)irradiated DPPP were characteristic of phenyl radicals. The MS spectra of DPPP and d
