Phenyl radical thermolysis and rate constants for phenyl + O{sub 2}

PDF Version Also Available for Download.

Description

The thermal decomposition of C{sub 6}H{sub 5}I has been used to prepare in-situ known initial concentrations of phenyl radicals at high temperatures. These can be degraded by direct decomposition at T > 1350 K giving H + C{sub 6}H{sub 4}. Using H-atom ARAS, rate constants for C{sub 6}H{sub 5} dissociation have been measured. Using the same ARAS technique, constants for C{sub 6}H{sub 5} dissociation have been measured. Using the same ARAS technique, the H- and O-atoms formed from the reaction, C{sub 6}H{sub 5} + O{sub 2}, have both been measured. The rate constant results are discussed along with lower T ... continued below

The rate constant results are discussed along with lower T measurements in terms of RRKM calculations using published ab initio electronic structure determinations of transition states.
