Abstract: | Centrifugal distortion analyses based entirely on high-quality infrared data are carried out for the ground vibrational states of H216O, H217O, and H218O. As a result of the analyses, the values of 27 rotation and distortion constants for each species are determined. By using these constants it was possible to improve considerably the accuracy of the literature values for rotational energy levels at high Jτ, especially for H217O and H218O. The experimental values for the energy levels are deduced from the observed rotational transitions constituting the fitted data. |
