Significance Solvent properties are in important consideration in many chemical reactions, including nucleophilic substitution reactions. Basic questions from students; resources for projects and reports. Views Read Edit View history. Articles related to solutions. De Schryver, A. The emission spectra of naphthalene NP —triethylamine TEA systems were measured under steady-state illumination conditions in some protic and aprotic solvent-tetrahydrofuran THF mixtures. Photoinduced electron transfer in solutions: Exciplex and radical ion pair formation free ebthalpies and their solvent dependence. Who is online. Their ability to dissolve salts depends strongly on the nature of the salt. The decrease in the intensity of band A with increasing solvent polarity is considered to be caused by the enhanced formation of an ion-pair parallel to the formation of an exciplex with increasing solvent polarity.
