查询词典 ethylene glycol

A study of Chemically Induced Dynamic Poiarization spectra is made, using a highly time resolved ESR, of photolized anthracenequinone radicals to determine the influence of surfactant micelles on the spin polarization of anthracenequinone anion. It is found that the CIDEP mechanism of photolization is mainly the radical pair mechanism of anthracenesemiquinone radical and of ethylene glycol ketyl R〓〓 or R〓 radical whose center is carbon in anthracenequinone/ethylene glycol system, but there is a certain amount of triplet state mechanism polarization.
