The reaction of NO with the peroxy radical CFC12CH202, and with CH3CFClO2 was investigated at 8-20 torr and 263-321 K by UV flash photolysis of CFCI2CH3/O2/NO gas mixtures The kinetics were determined from observations of the growth rate of the CFC12CH20 radical and the decay rate of NO by time-reso

β¦ Synopsis
The rate constant for the reaction CH302 + NO2 -(products) has been measured directly by flash photolysis and kinetic spectroscopy. At room temperature and a t total pressures between 53 and 580 Torr, k:, = (9.2 f 0.4) X lo8 liter/mole sec so that the rate of formation of the probable primary product peroxymethyl nitrate (CH302N02) may be significant in urban atmospheres.
