    • Abstract

       

      Suppan (1983Chemical Physics Letters94 270) has proposed an equation to estimate the excited state electric dipole moment from absorption and fluorescence solvatochromic shifts and applied it to the first excited stateL(b) of aniline. A better approach to this problem is proposed here, which avoids the assumption in respect of μe making an angle with Δμeg = μe − μg; μg being ground state electric dipole moment. This approach is expected to give a better estimation of the electric dipole moment of a molecule when it is electronically excited. On testing this approach for aniline in its first excited state μe turns out to be 5.31 D.
