查询词典 peroxy

Ten variously substituted benzoyl peroxides were synthesized for Raman spectrometric identification both in solution (CCl 2FCClF 2) and solid state. Different to infrared spectra, Raman spectra have been proved to be a useful characterization of the highly symmetric peroxy bond in diacyl peroxides.
