The dye molecule in a saturated hydrocarbon solvent (instead of the vacuum) is taken as reference state: the a-electrons of solute and solvent are treated as a continuous medium of dielectric constant E o = 2. The n-electrons of the solute are assumed to be immersed in this medium. Solvent shifts O:

Absorption and fluorescence spectra of four coumarin laser dyes, Coumarin 440 (C440), Coumarin 450 (C450), Coumarin 466 (C466) and Coumarin 151 (C151), have been recorded in binary mixtures of DMSO and water at room temperature (298 K) to study the solvent effect and to evaluate the ground and excit
