Pressure broadening of oxygen fine structure lines by water. (March 2015) - Koshelev, M.A.
Abstract: The results of measuring water broadening coefficients of oxygen fine structure lines are considered. Together with the data from the work [Drouin BJ, et al. JQSRT 2014;133:190–8] they provide accurate and reliable information for atmospheric applications. Water pressure shifts are shown to be less than 15 kHz/Torr. The results of cross-checking the pressure shifts from the work [Drouin BJ, et al. JQSRT 2014;133:190–8] are presented. Highlights: Accurate measurements of water broadening of oxygen fine structure lines. Rotational dependence of water broadening parameters is analyzed. Pressure shifts are shown to be negligible. Cross check of line shifts is performed.
