FURTHER STUDY ON TEMPERATURE, DENSITY, AND PERTURBER DEPENDENCES OF ABSORPTION OF 3.39-MU-M HE-NE-LASER BY METHANE

In order to supplement the information on the perturber dependence of absorption at 3.39 mu m of the He-Ne laser by methane, the decadic mol ar extinction coefficients of methane diluted with helium, hydrogen an d carbon dioxide have been measured. The broadening data (s) gamma 1 ( CH4-X)/(s) gamma 1(CH4-Air) and beta 1(CH4-X) for He-1 H-2 and CO2, wh ich are available in a wide range of temperature (300-1000 K), are pro posed.
