✦ Synopsis

When studying weak molecular interactions (charge-transfer complexes) it is frequently necessary to use high concentrations of one of the interacting species in order to determine physico-chemical properties of these associations. Therefore the reliability of the results obtained might be questionable. In fact their concentration dependence has been established and the anomalies observed have been interpreted in various terms such as deviation from ideality, non-validity of Beer's law, presence of higher-order complexes, change of solvent coordination number, contact interactions, etc.. . (1) . We wish to propose here a new theory called"the Competitive Preferential Solvation Theory" (COPS theory), which can easily account for these
