32. Despite the fact that a change in the dipole moment of the dye by polarization was taken into account in determining the dipole moment of the dye by the Onsager theory, the solvent-dependent changes of these quantities have never been addressed in detail, and the studies were carried out almost exclusively in the weakly polar solvents cyclohexane, decalin, benzene, diisopropyl ether, and 1,4-dioxane: W. Baumann, Z. Naturforsch. A 1983, 38, 995-1002.

40. There is also a good linear correlation with the empirical π* solvent polarity scale (see reference [1]) for dye 1.
41. Based on a single-crystal X-ray analysis for dye 1 (to be published elsewhere) and NMR and molecular modeling studies for dyes 1-3, a planar X-S cis configuration is reasonable for these dyes.
42. Owing to the very high field strength, such experiments must be carried out with caution and in carefully dried solvents, in particular for the more polar solvents.
