In this study, a solvent-polarizable model in response to solute polarization is proposed, which is coupled with a three-dimensional reference interaction-site model theory. The charge-response kernel is used to describe solvent polarizability, and four different coupling schemes are assessed. The most feasible behavior scheme among them is the one that incorporates responses not only to solute polarization but also to solute-induced solvent polarization. The numerical results indicated that solvent molecules near the polar solute show significant polarization, and therefore, the model proposed here is useful for considering the solvation process and thermodynamics of polar solute molecules..

Ryosuke Ishizuka, Norio Yoshida, Extended Molecular Ornstein-Zernike Integral Equation for Fully Anisotropic Solute Molecules: Formulation in a Rectangular Coordinate System, The Journal of Chemical Physics,], 139, 084119, 2013.08, An extended molecular Ornstein-Zernike (XMOZ) integral equation is formulated to calculate the spatial distribution of solvent around a solute of arbitrary shape and solid surfaces. The conventional MOZ theory employs spherical harmonic expansion technique to treat the molecular orientation of components of solution. Although the MOZ formalism is fully exact analytically, the truncation of the spherical harmonic expansion requires at a finite order for numerical calculation and causes the significant error for complex molecules. The XMOZ integral equation is the natural extension of the conventional MOZ theory to a rectangular coordinate system, which is free from the trunca- tion of spherical harmonic expansion with respect to solute orientation. In order to show its appli- cability, we applied the XMOZ theory to several systems using the hypernetted-chain (HNC) and Kovalenko-Hirata approximations. The quality of results obtained within our theory is discussed by comparison with values from the conventional MOZ theory, molecular dynamics simulation, and three-dimensional reference interaction site model theory. The spatial distributions of water around the complex of non-charged sphere and dumbbell were calculated. Using this system, the approxi- mation level of the XMOZ and other methods are discussed. To assess our theory, we also computed the excess chemical potentials for three realistic molecules (water, methane, and alanine dipeptide). We obtained the qualitatively reasonable results by using the XMOZ/HNC theory. The XMOZ the- ory covers a wide variety of applications in solution chemistry as a useful tool to calculate solvation thermodynamics..
