Abstract:
The motion of an aerosol particle due to resonant optical radiation is studied. Radiation is absorbed velocity-selectively by molecules of one of the components of a gaseous mixture. Equations are derived for photophoretic force and velocity in the free molecule regime. The dependence of these characteristics on detuning the radiation frequency from an absorption line center and on accommodation and transport characteristics of exited and unexcited molecules is analyzed.
