Intense nonlinear-optics excitation of completely symmetric vibrations of polyatomic molecules: Study of the Fermi resonance and other anharmonic interactions
Gladkov S. M. , Karimov M. G. , Koroteev N. I.
Intense two-frequency laser pumping has been used for the selective excitation of up to 35% of the C02 and SF6 molecules in the samples from the ground state to completely symmetric vibrational states. It has been shown by a direct experiment, for the first time, that the Fermi-resonance states 10°0 and 02°0 of COa molecules are not strongly bound kinetically. The kinetics of the collisional excitation of 0220, 03'0, 0330, etc., states of C02 has been studied, and the corresponding reaction rates have been determined.
