The highly reliable potential energy function for the ground electronic state of the NaFH system based on the ab initio multi-reference configuration interaction calculations [M.S. Topaler, D.G. Truhlar, X.Y. Chang, P. Piecuch, J.C. Polanyi, J. Chem. Phys. 108 (1998) 5349; V. Špirko, P. Piecuch, O. Bludsky, J. Chem. Phys. 112 (2000) 189] is used to calculate the energies, widths, and dissociation pathways of the quasi-bound states of the Na⋯FH van der Waals molecule. Although emphasis is placed on the quasi-bound states resulting from vibrational excitation of the HF fragment in the complex, the bound states and the quasi-bound states, in which the HF fragment is not excited, are investigated as well. The study focuses on assessing the reliability of the earlier stabilization calculations [V. Špirko, P. Piecuch, O. Bludsky, J. Chem. Phys. 112 (2000) 189] by performing independent close-coupling calculations for the outgoing scattering waves of the NaFH system. The probabilities of decay of the Na⋯FH ro-vibrational resonances into various Na+HF(v,j) channels provide new insights into the dynamics of dissociation of the Na⋯FH complex.
