    The tunneling splitting of (HF)2 has been calculated by semiclassical adiabatic reaction-path methods, employing a small-curvature approximation for the effective mass along the tunneling path. The calculations include all six vibrational degrees of freedom and are based on the partly ab initio,...

    The diffusion Monte Carlo method is used to simulate vibrational states for HF and DF monomers and dimers. Ground state energies, dissociation energies, and vibrational motions are discussed on the basis of the simulations. Vibrational frequencies for the dimer are calculated using a mean field,...

    An HF nozzle beam and a cw HF laser beam in a coaxial and antiparallel arrangement facilitated exciting HF molecules vibrationally in v=1,J up to the saturation limit. A beam consisting exclusively of monomeric HF was generated by heating the beam source to 600 K and was confirmed using a mass...

    The hyperfine structure has been resolved for the two J=0→1 transitions of (DF)2, for the low frequency J=0→1 transition of (HF)2, and for the J=0→1 transition of the mixed species HFDF. Also, the J=0→1 transition and hyperfine structure were observed for the other...

    We present full six-dimensional calculations of the bound states of the HF dimer for total angular momentum J = 0,1 and of the quasibound states for J = 0 that correspond with vibrational excitation of one of the HF monomers, either the donor or the acceptor in the hydrogen bond. Transition...

    Systematic studies of the ability of a broad family of density functional methods applied to hydrogen-bonded complexes have been carried out on the hydrogen fluoride dimer. Specifically, calculations have been performed using basis sets of triple-zeta quality with diffuse functions and multiple...
