Molecular Spectroscopy and Structure

Five bands (ν1 + 2ν2 + ν3 + 2ν40, ν1 + 3ν2 + 3ν41 + ν51, ν2 + 3ν3, 2ν2 + 2ν3 + ν41 + ν51, and 2ν1 + ν2 + ν3) were restudied by means of near-infrared diode laser spectroscopy to obtain more precise upper state molecular constants. Intensity measurements were carried out for the four bands, ν1 + 2ν2 + ν3 + 2ν40, ν1 + 3ν2 + 3ν41 + ν51, ν2 + 3ν3, and 2ν1 + ν2 + ν3, to obtain the transition band dipole moments. The latter values were found to be 1.42(27) × 10−4, 1.551(28) × 10−4, 2.474(35) × 10−4, and 1.067(22) × 10−4 D, respectively, for each of the four bands.
