✦ Synopsis

The photooxidation of acrylonitrile, methacylonitrile, and allylcyanide in the presence of NO was studied in parts per million concentration using the long-path Fourier transform IR spectroscopic method. The stoichiometry of the OH radical initiated oxidatiy? of methacrylonitrile was established as (OH) + CH,=C(CH,)CN + 2N0 + 20, + HCHO + CH,COCN + 2N0, + (OH). The yield of HCHO for acrylonitrile and allylcyanide was found to be ca. 100 and 80%, and the stoichiometric reactions were assessed to proceed, (OH) + CH,=CHCN + 2N0 + 20, 2 HCHO + HCOCN + 2N0, + (OH) and (OH) + CH,=CHCH,CN + 2N0 + 20, 2 HCHO + HCOCH,CN + 2N0, + (OH), respectively. These results revealed that the reaction mechanism for these unsaturated organic cyanides are analogous to that of olefins.

We have studied the reaction mechanism for both the NO 3 -and OH-initiated atmospheric oxidation of three cresol isomers, p-cresol, m-cresol, and o -cresol, in the presence of high NO 2 concentration. We have focused on the reaction mechanism leading to ringretaining products. Geometries of the reac

## Abstract The mechanism of the OH‐initiated oxidation of β‐pinene in the presence of NO has been investigated using a discharge‐flow system at 5 Torr and 300 K. OH radical concentrations were measured as a function of reaction time by laser‐induced fluorescence (LIF). The rate constant for the OH
