Abstract

Theoretical analysis of rotational energy levels for the first decade of interacting vibrational states-(201)-(003)-(121)-(041)-(300)-(102)-(220)-(022)-(140)-(060)-of the H2 18O molecule is made. The improved effective rotational Hamiltonian is used in the fitting of experimental energy levels [J.-P. Chevillard, J.-Y. Mandin, J.-M. Flaud, and C. Camy-Peyret, Canad. J. Phys.65, 777-789 (1987)] and the rotational, centrifugal, and resonance spectroscopic constants of this Hamiltonian are obtained. Calculated and initial experimental energy levels are compared.
