Figure 2.

Absorbance for different concentrations of 0.05, 0.5, 5 and 50 mol/l of the hypothetical material assuming c ⋅ d=50 cm ⋅ mol/l: a) conventional dispersion formula, b) conventional dispersion formula assuming additionally a redshift according to $\tilde{\nu }{{}^{\text{'}}}_{0i}=\sqrt{{\tilde{\nu }}_{0i}^2-\frac{c}{3}{S}_i{{}^{*}}^2}$ , c) Lorentz‐Lorenz formula [Eq. (10)] in combination with (18), d) Same as c) but with hypothetical solvent. Note that for d), in contrast to a)–c), a constant d=10⁻⁶ cm was chosen and that the range of the y‐axis is different.
