Experiments were continued to study the physical nature of the drift motion of SF6 molecules under the action of radiation from a repetitively pulsed CO2-laser. To explain the physical nature of the effect, such phenomena as a change in the transport cross-section during laser excitation of molecules, the phenomenon of optical tweezers, thermal diffusion are considered. However, the most reasonable physical explanation of the nature of this effect is the fractionation of a gas mixture as a result of gas dynamic diffusion at the front of a cyclically expanding gas (a variant of barodiffusion). Keywords: fractionation of gas mixture, thermal diffusion, optical tweezers, barodiffusion.
