Abstract
We studied in detail the IR multiple-photon (MP) absorption in the quasicontinuum of SF6 molecule in the vicinity of the frequency of the mode ν3. The molecules were preliminarily raised to the quasicontinuum by means of a pump laser pulse, and then we measured their IR MP absorption of a probe pulse, depending on its fluence and frequency ω2, as well as on the initial excitation level (vibrational temperature) of the molecules. The latter was varied from room value to Tvib = 1700 K. The frequency ω2 was varied in the range 884.18−944.2 cm-1. The IR MP absorption spectra measured, as well as the fluence and Tvib dependences of MP absorption for various ω2, are intended for making a comparison with the results of the theoretical modeling of the IR MP excitation dynamics and obtaining the spectral characteristics of the IR transitions of the SF6 molecule in the quasicontinuum.
