On the possibility of the effective isotope-selective infrared dissociation of $^{235}$UF$_6$ molecules vibrationally excited by bichromatic laser radiation

Using the spectroscopic data on the $^{235}$UF$_6$ and $^{238}$UF$_6$ molecules and on the lasing frequencies of CF$_4$ and para-H$_2$ lasers and recent results, a method has been proposed to increase the efficiency of the isotope-selective infrared laser dissociation of $^{235}$UF$_6$ molecules under nonequilibrium thermodynamic shock conditions. The method involves two processes: (i) the resonant multiphoton excitation of $^{235}$UF$_6$ molecules to the $3\nu_3$ or $2\nu_3$ vibrational states by the bichromatic infrared radiation of two CF$_4$ or para-H$_2$ lasers and (ii) the irradiation of $^{235}$UF$_6$ molecules with SF$_6$ molecules serving as sensitizers resonantly absorbing the radiation of these lasers. The essence of the method has been described. Schemes and parameters for isotope-selective dissociation of $^{235}$UF$_6$ molecules using this method has been presented.
