Dispersion of Ultrafast Optical Kerr Effect in No-aggregation Phthalocyanine Molecules

We report dispersion property for femtosecond optical Kerr effect in the solutions of no-aggregation 16 (trifluoro ethoxy1) vanadyl phthalocyanine in the wavelength range of 850-770 nm. The optical Kerr effect spectrum shows a broad near-resonant enhancement on the third-order nonlinear optical response of the molecule.
