AbstractThe effect of n-heptane and n-butanol mixtures upon the absorption and fluorescence spectra of donor-acceptor-substituted trans-stilbenes is investigated. The electronic-vibration spectra of these compounds depend upon the magnitude of the electric dipole moments in the ground and excited states, upon the relation between the mean lifetime τfw and the time of dielectric relaxation τR, and upon the environment around the solute molecule.

Abstract The electric dipole moments in the ground μg, and excited states μe of the fluorescent probes BADAN (6-bromoacetyl-2-dimethylamino-naphthalene) and ACRYLODAN (6-acrylolyl-2-dimethylamino-naphthalene) are determined from the solvatochromic shifts of their absorption and fluorescence spec­tra for two Onsager interaction radii (a = 4.2 and 4.6 Å). The obtained values of μg and μe for BADAN are comparable to those of PRODAN, while for ACRYLODAN they are distinctly greater.

Abstract The electric dipole moment of yt-Base calculated by the CNDO/S and JNDO/S method is μg = 3.42 D and μg = 3.74 D in the ground state and μe = 4.41 D and μe = 5.67 D in the first excited ππ*-state, respectively, μg and μe being nearly antiparallel. Measurements of absorption and fluorescence spectra of yt-Base in aprotic solvents of different polarity yielded μg = 3.8 D and μe = 4.3 D and the directions of dipole moments were found to be nearly antiparallel.This comparison may be considered as an indication for the ππ* character of the observable first excited state, although the CNDO/S-and JNDO/S-calculations predict a nπ*-state as the lowest lying excited state
