This project measured absorption and fluorescence spectra for the series of moledul3w, 2, n-di-(p-dimethylaminobenzylidene) cycloalkanones (n=5-8), in a variety of solvents in order to determine if a shift towards shorter wavelengths, with increasing ring size, is observed for the long wavelength, charge transfer (CT) transition. Also Lippert plots were constructed in order to determine the influence ring size on the degree of CT and the change in dipole moment for the S-S (CT) transition. Molecular modeling calculations were carried out for the purpose of computing ground state structures, dipole moments, and Onsager cavity radii.
