Abstract: 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 and shifting coefficients for different isotopologues coincide within the error margins. The broadening coefficients are in good agreement with those reported previously, however they have a smaller error, about 1%. The shifting coefficients are reported for the first time. The obtained line intensities of both isotopologues are in reasonable agreement with values published earlier.
