Vibration-rotation band strengths and dipole moment function of the H⁷⁹Br molecule

From the data on the line strengths, the band strengths of the 1-0 and 2-0 vibration-rotation bands of H 79 Br molecule have been respectively calculated to be 10.65+or-0.22 and 0.174+or-0.008 cm -2 atm -1 at 294 K. From the vibrational matrix elements involving the Morse and anharmonic oscillator wave functions, two sets of values for the dipole moment coefficients M 1 and M 2 have been calculated. They are M 1 =0.316 debye AA -1 , M 2 =0.518 debye AA -2 or M 1 =0.344 debye AA -1 , M 2 =-0.096 debye AA -2 . These values are compared with the values reduced from the low-resolution data.
