benzo[a]xanthenes has been investigated by using the Lippert–Mataga and Reichardt–Dimroth methods. Bakhshiev's and Kawski–Chamma–Viallet's correlations were used to determine the excited state dipole moment, ground state dipole moment and their ratio. The nature and extent of solute–solvent interactions were described by multi-linear correlation using the three-parameter Kamlet–Taft and the new four-parameter Catalán
