    • disp is the same for absorption and emission and is merely responsible for a uniform shift of both lines. Since our focus here on the Stokes shift and the width, the dispersion shift can be left out in considering the solvent effect on spectral band shapes.

    • Anisotropic polarizabilities from ab initio calculations (see footnote g in Table 2) were used to test the dependence of the calculated parameters on the solute's polarizability anisotropy. Anisotropic polarizability leads to a higher magnitude of the fitted solute radius but generates almost equivalent band shapes when the fitted radius is used.

The latter was obtained from the deconvolution of the optical line with the line in 2-methylbutane, according to eq 54. This procedure assumes decoupling of the vibrational and solvent modes, which does not hold for C153. In our analysis, we used therefore the total experimental Stokes shifts and widths.
