摘要：

The Cavity Ring-Down Spectra (CRDS) of hydrogen chloride were recorded in the 12,943-13,295 cm -1 region with sensitivity of 4 x 10 -11 cm -1. The lines P(4) - P(12) of the 5-0 band of two H35Cl and H37Cl isotopologues were assigned in these spectra. The positions, intensities, self-broadening and self-pressure -induced shift coefficients of these lines were measured. The measured line positions are in a good agree-ment with those presented in the HITRAN2020 database. The measured line intensities are 1.3 times greater than those from the HITRAN2020 database. The measured self-broadening coefficients are in a good agreement with the HITRAN2020 values for the small angular momentum quantum numbers and slightly exceed the HITRAN2020 values for the large angular momentum quantum numbers.& COPY; 2022 Elsevier Ltd.
