Infrared emission spectrum of NaBr

The infrared emission spectrum of Δν = 1 bands of NaBr monomer has been observed with a Fourier transform spectrometer. The ν= 1-0 to 5-4 vibration—rotation bands for both Na 79Br and Na 81Br were assigned in the wavenumber range between 225 and 315 cm −1. These infrared data combined with millimete...

Description
Summary:The infrared emission spectrum of Δν = 1 bands of NaBr monomer has been observed with a Fourier transform spectrometer. The ν= 1-0 to 5-4 vibration—rotation bands for both Na 79Br and Na 81Br were assigned in the wavenumber range between 225 and 315 cm −1. These infrared data combined with millimeter-wave data from the literature were analyzed with a least-squares fit to a Dunham potential function with only seven parameters. ω e (Na 79Br) has been determined to be 298.7377 (43) cm −1 with one standard error in parentheses. Thirteen Dunham Y ij coefficients have been derived for each of the two isotopic species from the Dunham potential function.
