摘要：

Comparison of the fluorescence kinetics of two dialkylaminobenzonitriles with different hindrance to planarity is used to extract information on the polar-solvent induced shape changes of the excited-state potential surface for TICT formation. The conical intersection between B* and A* states is shown to move to smaller twist angles as solvent polarity increases.
