VIBRATIONAL-ROTATIONAL ENERGY LEVELS OF H214O, H215O, H216O, H217O, H218O AND H219O

The paper presents an analysis of the vibrational-rotational energy spectrum of water isotopologues H214O, H215O, H216O, H217O, H218O AND H219O up to J=20 and energy of 25000 cm-1. Calculations of the H217O and H218O levels for such a data configuration are presented for the first time. All calculations were performed based on the high-precision potential energy surface of the molecule by Bubukina et al. 2011 using the DVR3D package. An analysis of the difference in energy levels of different isotopologues corresponding to the same energy level was performed.
