Determination of Self-Broadening Coefficients of CO, Using CO(2) Laser Radiation at 10.6 micro
Abstract:
Essentially monochromatic radiation with a frequency corresponding to the frequency of the line center of the P(20) line of the 961-cm(-1) CO(2) band was obtained from a CO(2)laser. Using this radiant energy, transmittances of CO(2) samples were measured as various broadening gases were added. Self-broadening coefficients of CO(2) relative to nitrogen, hydrogen, helium, and argon were determined from the measurements characterizing the transmittance only at the line center; from these measurements ratios of optical collision diameters are calculated.
