The solvent effect in a series of polar and non-polar solvents of varying dielectric constants and refractive indices has been investigated by studying electronic spectra (S1 band) of a series of exalite laser dyes at room temperature (25 1oC).
These data are used to determine the magnitude (me) and direction (q) of the electric dipole moments in the first electronically excited state.
The results indicate that the observed band systems in these compounds may be attributed to p*p transition.
