Solvent effect on UV/Vis absorption and emission spectra in aqueous solution based on a modified form of solvent reorganization energy

- Novel form of solvatochromic shifts for electronic spectra are proposed.
- The lowest n → π∗ and π∗ → n transitions for acrolein in water are calculated.
- The contributions to the shift are discussed.
- Electrostatic polarization is found to be crucial for electronic spectra.
