Abstract

Measurements of the average number of photons absorbed by SF₆ from unfocused CO₂ laser pulses are reported as a function of integrated intensity, pressure, and laser wavelength. Measurements extend from very low excitations to well above the dissociation threshold. The importance of anharmonic splittings, which are mixed extremely rapidly by collisions, is emphasized by the pressure and wavelength dependences.
