Abstract A series of chemical kinetic mechanisms, each of which describes the formation of photochemical smog from nitrogen oxide and multiple organic precursors has been developed. The most condensed version of the mechanism series now available is known as CBM-IV (Carbon Bond Mechanisms). The formulation and testing of CBM-IV is the subject of the report. This mechanism has been carefully tested against results obtained with an expanded CBM mechanism and several intermediately condensed mechanisms to ensure that the condensation steps did not contain compensating factors and to verify that the CBM-IV performed well under a range of conditions. The condensation of the expanded mechanism was tested in an incremental manner by simulating seven days of outdoor smog chamber data from two different experimental facilities. The data provided a wide range of time, temperature, light intensity, and concentration conditions for comparing simulation results from increasingly condensed mechanisms with the expanded mechanism. This approach was used to minimize compensating errors and to verify the operating boundaries of the mechanism at each condensation step. This development yielded a mechanism containing 28 species and 70 reactions.
