Nonequilibrium dissociation of a molecular gas under the action of infrared resonance laser radiation

A theoretical analysis is made of the nonequilibrium dissociation of molecules under the action of laser radiation whose frequency coincides with the frequency of one of the vibrational modes of a molecule. Equations are obtained for the relationship between the dissociation rate constant and the vibrational temperature, on the one hand, and the laser radiation flux density, on the other. It is assumed that the characteristics of the molecules and the gas temperature are known. The vibrational states of molecules are considered in the harmonic oscillator approximation and also making allowance for the anharmonicity.
