It is demonstrated that the CH radical can be generated with sufficiently high concentrations by means of the multiphoton dissociation of CHBr//3 at 193 nm for kinetic measurements. The formation and decay of the CH radical was monitored by the laser-induced fluorescence technique using the (A**2 DELTA implied by X**2 pi ) transition at 430 nm. Several rate constants for the reactions relevant to high temperature hydrocarbon combustion have been measured at room temperature. One of the key reactions, CH plus N//2, has been shown to be pressure-dependent, presumably due to the production of the CHN//2 radical at room temperature.
