Nonequilibrium excitation of the vibrational spectrum of boron trichloride by CO₂ laser radiation

N. V. Karlov, N. A. Karpov, Yu. N. Petrov


Abstract: It was found experimentally that the action of resonant CO₂ laser radiation produced nonequilibrium populations of the vibrational levels of BCl₃. The average energy needed to reach high vibrational levels and dissociation threshold was less than the equilibrium (thermal) energy of the excitation process.
