title: Solvent influence on the electronic absorption spectra (EAS) of 1,6-diphenyl-1,3,5-hexatriene (DPH).
abstract: The electronic absorption spectra of 1,6-diphenyl-1,3,5-hexatriene (DPH) were recorded in a great number of solvents with various physico-chemical properties. The dependence of the wavenumber in the maximum of the DPH vibronic bands on the solvent dispersion function demonstrates the prevalence of the dispersion interactions in the studied solutions. Some electro-optical parameters of DPH molecule were computed by HyperChem and were correlated with the results obtained from the solvatochromic effects on DPH. The polarizability in the electronic excited state of DPH has been estimated from the solvatochromic effect.
