Abstract

Dependence of E_T(30) of solvent parameters on relative permittivity (ε) and refractive index (n) of solvent has been found for forty solvents in the form E_T(30)=29.87 + 72.03 (ε - 1/(2ε + 1)-29.16(ε - 1) (n ² - 1)/(2ε + 1) (2n² + 1), the correlation coefficient being 0.958. Relation has been discussed between E_T(30) and π solvent parameters and significance of the term (ε - 1). (n² - 1)/(2ε + 1) (2n² + 1) has been tested for evaluation of solvent effects in electronic spectra.>
