摘要：

Solvent polarity effects on a disubstituted biphenyl have been investigated through IR, Raman, UV-visible spectroscopies. The results are interpreted in the light of some empirical and density functional electronic structures calculations. The vibronic structure has been determined and the normal modes in the finger print region have been assigned. This study opens the way to the exploitation of vibrational spectroscopy in the elucidation of the complex phenomena occurring when highly dipolar chromophores are embedded in dielectric media for applications in nonlinear optics (NLO).
