Good Agreement

A variation of the temperature changes the static dielectric constant (ε) and the refractive index (n) of solvents and, in conjunction with the measurement of solvent shifts of absorption and fluorescence maxima, allows the investigation of dipole moment changes of solutes in the excited state. For this purpose, investigations of the temperature dependences of ε and n of some pure and mixed solvents of different polarities have been made. It is found that the excited dipole moments of indole, 1,2-dimethylindole, 2,3-dimethylindole and tryptophan obtained from the shifts of the fluorescence maxima in mixed solvents at high temperatures are in good agreement with those obtained in other ways.

Nonpolar Solvents

An equation which allows for the determination of the dipole moment and polarizability of polar substances via the dielectric constant of solutions of the substance in nonpolar solvents is tested using different solute–solvent pairs. The results indicate that this equation provides good values of the dipole moment and of the polarizability if the solvent is correctly chosen. [Journal translation]
