Abstract:The spectrum of water vapor heated in an absorption cell at 60°C has been recorded on a Fourier transform spectrometer between 4200 and 5000 cm?1. A thorough analysis of the spectrum has been performed, leading to an improved and extended set of rotational energy levels for the (030) vibrational state. Intensities of about 50 lines of the 3ν2 band are reported and a calculation of these intensities has been performed allowing the determination of the vibrational matrix element of the transformed dipole moment operator.
