✦ Synopsis


Rcreivcd 7-h May 19%; in final form 18 July 19S3 The thcrmod? namic properties and site-site distribution functions of mixtures of non-spherical molecules are obtaincd by Vontc Carlo simulation. A non-spheriwl rcfcrcncc-system perturbation theory based on the RIShI equation is developed to predict thcsc rcsuk The ageemcnt bewecn theory and simulation for the thermodynllmic properties is cncour-:wing_ Important differences in the relative peak heigdlts of the site-site distribution functions from theory and simulation xc Attnbuted to the role of attrxtivc forces in dctcrminins local structure in the fluid mixtures, where the volumes of the conqwncnt< arc similar but the well depths differ.

A simple method for incorporating bond-length constraints in Monte Carlo simulations of cyclic and linear molecules is described. As an example, the conformational behavior of five even-numbered cyclic alkanes is studied using Monte Carlo simulation and the MM2 force field.
