Zusammenfassung FTIR spectra of the 2-0 band of HCl have been measured in the 5300-5900 cm-1 spectral region at 15 different pressures (0.05 - 2.5 bar) and at a spectral resolution of 0.07 cm-1. For the first time, reliable and consistent self-induced broadening and shift coefficients for the complete HCl 2-0 band have been reported. Line intensities determined from a robust regression analysis with improved uncertainties are also presented. Compared to previous laser-based measurement for the R3 line {Ortwein et al., Applied Physics B: Lasers & Optics, 100:341-7 (2010)}, our newly measured γ_self coefficient and line intensity are 1.35% and 0.10% larger, respectively. Hartmann and Boulet {Hartmann & Boulet, JCP 113, 9000 (2000)} developed a formalism describing the relation between the shift coefficients of different vibrational bands and successfully applied to Ar-HF system. Our newly measured self-induced shift coefficients suggest that the H-B formalism is not suitable for describing the HCl-HCl collisional system.
