The equivalent widths, the line strengths, and the squares of the dipole matrix elements of the 2–0 vibration–rotation band lines of the H79Br molecule are measured. The measurements are made on a high-resolution infrared grating spectrometer which could completely resolve the two isotopic lines of H79Br and H81Br. This is the first time the high-resolution work on the intensities of the HBr molecule has ever been presented. The present data are compared with the earlier work obtained using a low-resolution spectrometer. It is found that the present values are considerably less than the earlier low-resolution values. The discrepancy between the two sets of results is attributed to the lack of resolution in the earlier investigations.
