Singularities of the SF6 absorption spectrum at high IR intensities
Basov N.G., Galochkin V.T., OraevskiI A.N., Starodubtsev N.F.
It is demonstrated experimentally that the frequency of the maximum of SF6 molecule absorption shifts to the long-wave region at high incident-radiation energies and at IR pulse durations exceeding the time of the vibrational-translation relaxation. An explanation is offered for the observed absorption-spectrum singularities.
