Abstract

We report the results of our femtosecond laser study of the photophysical and photochemical properties of the DCM styrenic dye. Our femtosecond pump-probe experiments using a white light continuum show a red shift of the gain spectrum and a blue shift of the S₁ yields S_n absorption band due to a fast reorganization of the solvent cage around the highly polar fluorescent first singlet excited state. There is no evidence of any locally excited (LE) to twisted intramolecular charge transfer (TICT) state transition.
