Abstract
The complete unambiguous spectroscopic assignment of rotational levels of the 000, 010, 100, 020, and 001 vibrational states of H2 18O up to J, K a = 30 is presented and discussed for the first time; it is based on the isotopically dependent Partridge and Schwenke potential energy surface (PES). The published experimental energy levels for these states have been analyzed on this basis. A comparison of the Partridge-Schwenke (PS) and Shirin, et al. calculated energy levels is also presented and discussed. The obtained results could be useful for the search and assignment of new highly exited states of H2 18O.
