The photodissotiation dynamics of NOC1 at 370 - 385 nm has been investigated by using the two-photon laser induced fluorescence (LIF) method to probe the NO photoproduct. The nascent NO is found vibrationally cold and rotationally hot. About 25% of the available energy is distributed on the NO rotational degrees of freedom and the rest goes into the translational degrees of the recoiling NO and Cl fragments. The rotational distribution of NO is shown to be of approximate gaussian-type and the distribution shape changes a little while the wavelengths of photolysis laser is varied. A modified impulsive model for photodissociation process is presented and the theoretical prediction is consistent with the experimental measurement.
