The broadening coefficients of SO2

Description

Recent experimental measurements and calculations were employed to update the self- and air- broadening coefficients of line transitions of SO2. A semi-empirical method based on the fit to the available experimental data was used to compute the air-broadening coefficients of SO2. The self-broadening coefficients of SO2 were updated using scaled semi-classical calculations from  Tasinato et al, J. Quant. Spectrosc. Radiat. Transf. 130 (2013) 233–248. .
