O2 concentrations in the carrier gas were in the range of (7.7-84) × 1014 molecule cm−3. The primary stable products detected were phenol, benzene oxide/oxepin and a not identified compound with the probable composition C5H6O. The yields of phenol and benzene oxide/oxepin were 0.12 ± 0.02 and 0.26 ± 0.06, respectively, being not affected by the experimental conditions. For benzene oxide/oxepin, a rapid consecutive reaction with O(3P) atoms was observed with a rate coefficient of k(295K) = (1.1 ± 0.1) × 10−10cm3 molecule−1s−1 measured at a pressure of 100mbar. A substance with the formula C6H6O2 (likely oxepin 4,5-epoxide or oxepin 2,3-epoxide), the isomers of muconaldehyde, as well as formic acid, acrolein and trans-butenedial were identified as products of the reaction of O(3P) atoms with benzene oxide/oxepin. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Berndt Torsten aut Böge Olaf aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/4/2004(2004-04-01), 391-404 0942-9352 218:4/2004<391 2004 218 zpch https://doi.org/10.1524/zpch.218.4.391.29202 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.4.391.29202 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Berndt Torsten aut NATIONALLICENCE 700 1- Böge Olaf aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/4/2004(2004-04-01), 391-404 0942-9352 218:4/2004<391 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
