Using the long path FT IR method, we made product studies of the photolysis of n-butyl nitrite (n-C4H9ONO) in ppm concentrations at 700 torr of air and 298 +/- 2 K.Unidentified HO-containing compounds as well as n-butyraldehyde (n-C3H7CHO) were detected.The results provide further evidence for the occurence of the following competitive uni- and bimolecular reaction paths for the ensuing n-butoxy radicals: intramolecular hydrogen-shift isomerization CH3CH2CH2CH2O. -> CH2CH2CH2CH2OH (1), and O2 reaction CH3CH2CH2CH2O. + O2 -> CH3CH2CH2CHO + HO2 (2).From the observed yield of n-C3H7CHO, the relative rate k₂/k₁ has been determined to be 0.23 +/- 0.03 (2?) at 700 torr of air.
