Abstract
Molecular dynamics (MD) simulations are carried out for liquid acetonitrile using a new six-site model for the solvent molecules. The recent force field of Cornell et al. ( J Am Chem Soc, 1995, 117, 5179) was used under the RESP approach to obtain the atomic charges. A new flexible all-atom solvent model was achieved whose density, heat of vaporization, and isothermal compressibility values are in good agreement with available experimental data, especially for a generic force field. Radial distribution functions are calculated and discussed to study the liquid structure in detail. © 2000 John Wiley & Sons, Inc. J Comput Chem 21: 901–908, 2000
