✦ Synopsis

The spectroscopic description of the vibrational excitations of the H 2 16 O molecule is presented in the framework of the su(2) vibron model approximation. Both Darling-Dennison and Fermi-like interactions are taken into account in the energy fit, where an rms deviation of 3.05 cm -1 for 58 experimental levels is obtained. We are able to establish for the first time a direct connection between the spectroscopic parameters and the molecular structure constants in the vibron model. To test the physical content of the potential constants, a comparison is made between the predicted and observed energies for H 2 18 O. In addition, an analysis of the transition intensities is presented.

Using very large basis sets, which can accurately describe the polarizability of Ni and Hz0 and the dipole moment of H,O, the dipole-induced-dipole interaction is shown to be more than 50% of the about 4.8 kcaVmole bonding. Dispersion is found to account for the remainder of the bonding; this is sig
