We present improvements and enhancements associated with a laboratory exercise designed for the physical chemistry curriculum which involves the study of solvatochromism and photo-induced intramolecular electron transfer.  Students measure the absorption and fluorescence spectra of related dyes in different solvents and analyze the data for each species to determine the difference in the dipole moment between their ground and excited electronic states.  Additionally, students perform molecular modeling to gain a better understanding of their results.  This exercise teaches students about the role of the solvent in photo-induced electron transfer processes.
