متن کاملThe structure and spectra of organic peroxy radicals.
Recent spectroscopic and computational work on organic peroxy radicals, RO(2), is reviewed and extended with an emphasis on radicals where R is an alkyl group. Detailed experimental spectral, structural relationships are developed and show the dependence of spectral properties on the number of carbon atoms in the radical, and its isomeric and conformeric structure. These empirical relationships...
متن کاملPermutation Reactions of Organic Peroxy Radicals in the Troposphere
Organic peroxy radicals are important intermediates in the atmospheric photooxidation of hydrocarbons. Laboratory studies indicate that these radicals react among themselves (permutation reactions) at rates which should compete with those for reaction with HO 2 and NO x under some atmospheric conditions. Using the available laboratory data, we have developed a simplified method of representing ...
متن کاملMeasurements of peroxy radicals using chemical amplification-cavity ringdown spectroscopy.
The peroxy radical chemical amplification (PERCA) method is combined with cavity ringdown spectroscopy(CRDS) to detect peroxy radicals (HO2 and RO2). In PERCA, HO2 and RO2 are first converted to NO2 via reactions with NO, and the OH and RO coproducts are recycled back to HO2 in subsequent reactions with CO and O2; the chain reactions of HO2 are repeated and amplify the level of NO2. The amplifi...
متن کاملRapid Hydrogen Shift Scrambling in Hydroperoxy-Substituted Organic Peroxy Radicals.
Using quantum mechanical calculations, we have investigated hydrogen shift (H-shift) reactions in peroxy radicals derived from the atmospheric oxidation of 1-pentene (CH2═CHCH2CH2CH3) and its monosubstituted derivatives. We investigate the peroxy radicals, HOCH2CH(OO)CR1HCH2CH3, HOCH2CH(OO)CH2CR1HCH3, and HOCH2CH(OO)CH2CH2CR1H2, where the substituent R1 is an alcoholic (OH), a hydroperoxy (OOH)...
