The absorption spectrum of 13C16O2 near 806Â nm has been recorded with a continuous-wave cavity ring-down spectrometer. Two cold bands and one associated hot band are observed in this region. The line positions of these bands are determined with an accuracy of 0.003Â cmâ1. The absolute line intensities have also been retrieved with an estimated accuracy of 4% for majority of the unblended lines. The vibrational transition dipole moment squared values and the empirical Herman-Wallis coefficients are determined for all the three bands. The comparison of the retrieved line positions and intensities to those given in the Carbon Dioxide Spectroscopic Databank shows large deviations in the line intensities of the 10052-00001 band. The effective dipole moment parameters describing the line intensities of 13C16O2 near 806Â nm are fitted according to the observed line intensities.
⺠High sensitivity Cavity Ring Down Spectroscopy of 13C16O2 between 12,272 and 12,463 cmâ1. ⺠Line positions and intensities of 169 transitions were obtained for three bands. ⺠Good agreement with the line position predictions of the effective Hamiltonian model.
