- Solvation Phenomena in Dilute Solutions: Formal Results, Experimental Evidence, and Modeling Implications

Abstract: We review the fundamentals underlying a general molecular-based formalism for the microscopic interpretation of the solvation phenomena involving sparingly soluble solutes in compressible media, an approach that hinges around the unambiguous splitting of the species correlation function integrals into short (nite)- and long (diverging)-ranged contributions at innite dilution, where this condition is taken as the reference system for the derivation of composition expansions. Then, we invoke the formalism (a) to illustrate the well-behaved nature of the solvation contributions to the
