“…The knowledge of accurate spectral line parameters (such as pressure broadening coefficients) of HCl [14][15][16] is important and required for HCl measurements in atmospheric remote sensing, biomass gasification process, semiconductor manufactory cleanroom and precision industrial emission monitoring application. Recently, advances in solid-state laser technologies have provided alternative Mid-IR light sources and enabled access to the strongest HCl transitions in the fundamental band [17], which are about 50 times stronger than at the 1.7 µm HCl first overtone band which we have previously studied [18,19].…”

We determine the CO2, N2, Ar, O2 and air pressure broadening coefficients of the H35Cl P(5) absorption line at 2775.77 cm−1 in the fundamental (1←0) band using a newly developed direct tunable diode laser absorption spectroscopy (dTDLAS)-based spectrometer employing a mid-IR interband cascade laser (ICL). For the first time, a reliable and consistent set of five different foreign pressure broadening coefficients for the same HCl P(5) line has been measured by a consistent metrological approach covering pressures from 100 to 600 hPa at temperatures of 294 and 295 K. The relative uncertainties of the stated CO2, N2, Ar, O2 and Air pressure broadening coefficients are in 1–3% range. The results are compared to previously available literature data—two broadening coefficients have been improved in accuracy and two have been determined for the first time in the sub 1000 hPa pressure range.

“…Except for the 2-0 band of HCl, the HX line lists are identical to those in HITRAN2016. For P10 to R10 lines of the HCl 2-0 band, line intensities, Einstein A-coefficients and self-induced broadenings have been updated with reference [91], whilst air-induced broadenings and shifts have been updated with reference [92].…”

“…5 показаны коэффициенты самосдвига других галоидоводородов. Самосдвиги HCl [21] часто меняют знак в P-ветви и сильно отклоняются от монотонного поведения, но остаются батохромными в R-ветви, начиная с R 2 (1). Значения для HCl в R-ветви практически совпадают со значениями для HBr и HI.…”

Spectra of HBr with a natural abundance of isotopologues were recorded in the region of the first overtone at room temperature at various sub-atmospheric pressures. The coefficients of self-broadening and shifting were found for two isotopologues of HBr. Both broadening coefficients and shifting coefficients for different isotopologues coincide with the error margins. The broadening coefficients are in good agreement with those reported previously, however have a smaller error, about 1%. The shifting coefficients are reported for the first time. The obtained line intensities of both isotopologues are in good agreement with values published earlier.
