| Abstract: | To study the nonlinear properties of a new-type photosensitizer Hypocrellin A in solution,we study fast process of HA＇s excited state in non-polarized and weak-polarized solutions Through the transit grating technology,we believe it results from the decay of transitional state（TS＊）produced by skeleton rearrangement.Its lifespan is 10.5 ps. |
