The potential energy surface for trimers of hydrogen fluoride is examined for multiple arrangements of the three-molecule cluster. Several established approaches to model the potential energy are examined, including a strictly pairwise additive poten

Isothermal−isobaric Monte Carlo molecular simulations are performed to estimate the vapor-phase fugacity coefficients of hydrogen fluoride and water in their mixtures, covering the full range of composition at experimentally known saturation temper

We apply isothermal-isobaric Monte Carlo molecular simulation to measure the vapor-phase fugacity coefficients and equation of state of three fixed-charge models of water: SPC/E, MSPC/E, and TIP3P. State conditions correspond to the experimental vapo

A molecular-orbital derived polarizable potential function is developed to model liquid and supercritical fluid hydrogen fluoride. The model is based on a novel application of a combined quantum-mechanical and molecular-mechanical (QM/MM) approach, w

Several variations of ab initio based molecular models for hydrogen fluoride (HF) are examined by Monte Carlo molecular simulation to determine their bulk-phase properties. The models are taken from the literature, and represent fits of functional fo

We present a method for accelerating convergence of Monte Carlo (MC) simulations of associating fluids and describe its application to a model for hydrogen fluoride. The new bias scheme preferentially attempts MC trials that lead to unbonding–bondi

We present a method for accelerating convergence of Monte Carlo simulations of associating fluids. Such fluids exhibit strong, short-ranged, orientation-specific intermolecular attractions which are difficult to sample via conventional molecular simu
