摘要: | Relaxation of electronic excited-state and vibrational dynamics in the electronic excited state in Ru(II)(TPP)(CO) [TPP=tetraphenylporphyrin] dissolved in N(2) bubbled benzene, O(2) bubbled benzene, N(2) bubbled chloroform and N(2) bubbled acetone were clarified using a sub-5fs laser pulse. The result showed that the transition energy from the (1)Q(x) states, consisting of the (1)Q(x(1,0))(pi,pi*) state (existing at 18800 cm(-1)) and (1)Q(x(0,0))(pi,pi*) state (existing at 17800 cm(-1)), to the (1)M state of six-coordinated ruthenium complex is lower than that of the five-coordinated ruthenium complex. The intersystem crossing (1)Q(x(0,0))(pi,pi*)->(3)(d,pi*) in the five-coordinate Ru(II)(TPP)(CO) in the solution was found to take place in about 1 ps. |
