Abstract
The high-resolution Fourier-transform spectrum of the D 2 16O molecule is recorded and analyzed in the region near 1.27 μ m (7360–8440 cm −1) where the bands of the V=3 ( V= v 1+ v 2/2+ v 3) polyad are located. A total of 2772 transitions have been assigned based on recent variational calculation of Shirin et al. [JQSRT 2008;109:549–58]. A set of 1094 energy levels (564 of which are new) is determined for nine vibrational states including those of newly reported (1 0 2) and (2 2 0) states. Calculations using an effective Hamiltonian are performed to establish reasonable ro-vibrational labeling of the observed energy levels. The latest variational calculation are found to agree well with the experiment for line positions (within 0.026 cm −1 on average); however, the calculated intensities for transitions to upper energy levels which are in close resonance with other states can be distorted.
