Abstract
A method and apparatus for spectroscopic gas analysis are provided. Two coherent beams of monochromatic radiation are directed through gaseous material. A tuning mechanism adjusts the frequency difference between the radiation beams to equal substantially the rotational frequency of a preselected constituent of the gaseous material. Radiation scattered by the gaseous material is received by a filtering mechanism adapted to transmit selectively an anti-Stokes signal generated coherently during scattering. The signal is received by a detecting mechanism which indicates the intensity thereof.
