The High-Resolution FTIR Spectrum of the nu(1) Band of DOBr.
Fourier transform infrared spectra of the nu(1) bands of DO(79)Br and DO(81)Br have been recorded with a resolution of 0.0055 cm(-1) in the frequency range of 2510-2800 cm(-1). A total of 1901 lines of the A/B hybrid-type bands of both isotopic species have been assigned and fitted to upper state rovibrational constants employing a Watson's S-reduced Hamiltonian up to sextic terms. The K(a) >/= 4 subband transitions were found to be perturbed and were not included in the fit. The unperturbed band centers for nu(1) of DO(79)Br and DO(81)Br are 2668.79211 +/- 0.00006 and 2668.78842 +/- 0.00005 cm(-1), respectively. The ratio of the vibrational dipole transition moments (µ(a):µ(b)) was found to be 1.30 +/- 0.04 for the band. Copyright 2000 Academic Press.
