摘要：
The ultrafast relaxation processes of hematoporphyrin derivatives porphyrin derivatives (HPD) in water have been studied by time-delayed four wave mixing with incoherent light (TDFWM-IL), and the approach of electron relaxation from the excited state to the ground state has been discussed. Based on the measurement of the absorption and TDFWM-IL, a short-lived charge separated state (CSS) is demonstrated. Furthermore, a simple dynamic model is given.
