Abstract

In this study, the analysis of vibrational-rotational energy levels of six oxygen isotopologs of water vapor H214O, H215O, H216O, H217O, H218O, and H219O is presented. The energy levels are calculated for the angular momentum J values from 0 to 20 and energies up to 25 000 cm–1. The calculated energy levels of H217O and H218O for such a data configuration are presented for the first time. All calculations were performed on the basis of the high-precision potential energy surface of the molecule by Bubukina et al. (I. I. Bubukina, N. F. Zobov, O. L. Polyansky, et al., Opt. Spectrosc. 110, 160 (2011)) using the DVR3D package.
