Коэффициенты самоуширения и сдвига линий в полосе первого обертона молекулы HBr

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.
