The vibrational dynamics of the F-(H2O) complex is studied using highly accurate six-dimensional molecular potential energy and dipole moment surfaces calculated at the CCSD (T)/cc-pVQZ and CCSD (T)/augcc-pVTZ levels with a multiresolution approach. The extent of mode-coupling is investigated with full vibrational configuration-interaction (FVCI) calculations. Coriolis coupling effects are also included with the aim to obtain quantitative agreement with the experimental data available. The vibrational absorption spectra of the molecule up to 4500 cm(-1) has been calculated from FVCI using the Lanczos method, and an assignment of the most important absorption bands has been provided with the aim to assist future experimental work on this system.

STRUCTURAL STABILITY AND ENERGETICS OF AS, SB AND BI MICROCLUSTERS - EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTION CALCULATION Katırcıoğlu, Şenay (Elsevier BV, 1991-08-09) The structural stability and energetics of As, Sb and Bi microclusters having 3-7 atoms have been investigated by using a recently developed empirical many-body potential energy function (PEF), which comprises two- and three-body atomic interactions. The PEF satisfies both bulk cohesive energy per atom and bulk structural stability exactly. It has been found that the most stable structures of As3, Sb3 and Sb4 microclusters are in linear form with D-infinity-h symmetry, Bi7 is in hexagonal pyramid form with ...
Metallization of the C-60/Rh(100) interface revealed by valence photoelectron spectroscopy and density functional theory calculations Wade, Abdou-Ciss; Lizzit, Silvano; Petaccia, Luca; Goldoni, Andrea; Diop, Djibril; Toffoli, Hande; Fabris, Stefano; Baroni, Stefano (AIP Publishing, 2010-06-01) The electronic structure of single and multiple layers of C-60 molecules deposited on a Rh(100) surface is investigated by means of valence photoemission spectroscopy and density functional theory calculations. The binding of the fullerene monolayer to the metal surface yields the appearance of a new state in the valence band spectrum crossing the Fermi level. Insight into the metallization of the metal/fullerene interface is provided by the calculated electronic structure that allows us to correlate the me...
Bosonic helium droplets with cationic impurities: Onset of electrostriction and snowball effects from quantum calculations Coccia, E.; Bodo, E.; Marinetti, F.; Gianturco, F. A.; Yıldırım, Erol; Yurtsever, M.; Yurtsever, E. (AIP Publishing, 2007-03-28) Variational Monte Carlo and diffusion Monte Carlo calculations have been carried out for cations such as Li(+), Na(+), and K(+) as dopants of small helium clusters over a range of cluster sizes up to about 12 solvent atoms. The interaction has been modeled through a sum-of-potential picture that disregards higher order effects beyond atom-atom and atom-ion contributions. The latter were obtained from highly correlated ab initio calculations over a broad range of interatomic distances. This study focuses on ...
Sorption and diffusion of carbon dioxide and nitrogen in poly(methyl methacrylate) Eslami, Hossein; Kesik, Melis; Karimi-Varzaneh, Hossein Ali; Mueller-Plathe, Florian (AIP Publishing, 2013-09-28) Molecular dynamics simulations are performed to determine the solubility and diffusion coefficient of carbon dioxide and nitrogen in poly(methyl methacrylate) (PMMA). The solubilities of CO2 in the polymer are calculated employing our grand canonical ensemble simulation method, fixing the target excess chemical potential of CO2 in the polymer and varying the number of CO2 molecules in the polymer matrix till establishing equilibrium. It is shown that the calculated sorption isotherms of CO2 in PMMA, employi...
STRUCTURAL STABILITY AND ENERGETICS OF SI4 ISOMERS - TOTAL ELECTRONIC-ENERGY CALCULATION Katırcıoğlu, Şenay (Elsevier BV, 1991-09-20) The structural stability and energetics of Si4 isomers have been investigated by using an empirical tight-binding (ETB) method. It has been found that the most stable Si4 microcluster is an exact tetrahedron with T(d) symmetry.
