Measurements of 4.2 μm CO2 pressure broadening by using an HBr chemical laser

The pressure broadening of CO2(0000→00°1) transitions has been studied by using an HBr chemical laser. By measuring the absorption of the HBr laser beams by CO2 gas, the coefficients of broadening have been obtained as a function of the rotational quantum number J. The coefficient is expressed as Δν= (5.2±0.5)−(0.05±0.01) J (MHz/Torr). This equation is in good agreement with data from other reports. From the measurement the Einstein A coefficient has been calculated as A= (1.3±0.2) ×102 (sec−1). The effects of He and N2 collision partners have been measured.
