Orientation of a molecular gas by resonance radiation, optical detection, and their applications in laser spectroscopy
The results are reported of an investigation of resonant optical detection in molecular gases. An analysis is made of the mechanisms responsible for the additional permittivity and static polarization of a gas under the action of resonance radiation and a static electric field. Resonant optical detection of OsO4 and SF6 molecules, pumped by CO2 laser radiation, was observed experimentally.
