Abstract

A resonant optoacoustic cell was used to determine the specific absorption coefficients of small HCl admixtures to atmospheric nitrogen at the DF laser lines P2(3), P2(4), and P2(5). The cell was calibrated using absolute absorption coefficients of N2O measured with a multipass absorption cell. Effects of corrosive action and the relatively long relaxation time of the HCl–N2 mixture were carefully eliminated. The measured specific absorption coefficients of 510, 15, and 1.4 m−1 atm−1 at laser lines P2(3), P2(4), and P2(5) agree well with values calculated from absorption line parameters and are in fair agreement with older experimental results.
