Abstract

All currently known line positions of hydrogen chloride molecule (HCl) in the region from 7.4 to 18075 cm^-1 were fitted. The reliability of the data sources as well as their consistency were analyzed. Some disagreements were found due to the systematic errors in determination of the line positions. New set of isotopically independent spectroscopic parameters was obtained and used for the calculation of vibration-rotation energy levels. A comparison of the calculated centers of lines with those of the Hitran database was done.
