The photochemical smog chemistries of ethene, propene, butene-1, trans-butene-2, n-butane, 2,3-dimethylbutane, and toluene NOx systems have been developed and tested with smog chamber data collected at the University of California, Riverside. The mechanisms are composed of critically evaluated kinetic data for the individual reactions to the extent possible. Where data on specific reactions were not available or were not at the appropriate temperature and pressures, thermochemical techniques were used to estimate or extrapolate existing data to obtain the desired rate data. Whenever thermochemical data were estimated to predict rate constants, error bounds were assigned to the estimates and the resulting rate constants. In only a relatively few cases was it necessary to vary the estimated rate constants within the error limits in order to optimize the agreement between computed and experimental concentration-time profiles. Given the kinetic information currently available this general approach minimizes the need for adjustment of rate constants and produces mechanisms that are valid representations of the homogeneous gas-phase chemistry of each of these hydrocarbons in photochemical smog formation.
