Abstract
Converged nine-dimensional vibrational eigenvalue calculations are reported for forty energy levels of (HF)2 for the case of zero total angular momentum. The effect of HF stretching motions on the van der Waals bound states is assessed by comparing the results to seven-dimensional calculations in which the monomer stretches are frozen. Coupling to the HF monomer stretches increases the tunneling splitting by a factor of 3.7, and it changes some of the other excitation energies by up to 4 cm-1.
