ABSTRACT
 
Interactions between pairs of molecules in solutions cannot be explicitly given by experimental transport coefficients such as intra- or mutual diffusion coefficients. But a microscopic interpretation of the transport properties exists, where velocity cross-correlation integrals (VCC) or distinct diffusion coefficients (DDC) are related to preferential, correlated motion among distinct molecules. Herein we review the ability of model systems to describe translation motions in real systems. Specifically, the comparison of new and old standards with a number of VCC and DDC corresponding to real systems proves the applicability of this procedure also to macro-molecule-solvent mixtures. Perspectives on the applications of further standards based on more complex interactions are also presented.
