Relaxation of electronic excited-state and vibrational dynamics in the electronic excited state in Ru II(TPP)(CO) [TPP=tetraphenylporphyrin] dissolved in N2 bubbled benzene,O2 bubbled benzene,N2 bubbled chloroform and N2 bubbled acetone were clarified using a sub-5fs laser pulse. The result showed that the transition energy from the 1Q x states,consisting of the 1Q x(1,0)(π,π*) state(existing at 18800 cm-1 ) and 1Q x(0,0)(π,π*) state(existing at 17800 cm-1 ),to the 1M state of six-coordinated ruthenium complex is lower than that of the five-coordinated ruthenium complex. The intersystem crossing 1Q x(0,0)(π,π*)→ 3(d,π*) in the five-coordinate Ru II(TPP)(CO) in the solution was found to take place in about 1 ps.
Relaxation of electronic excited-state and vibrational dynamics in the electronic excited state in Ru II (TPP) (TPP = tetraphenylporphyrin] dissolved in N2 bubbled benzene, O2 bubbled benzene, N2 bubbled chloroform and N2 bubbled acetone were clarified using a sub -5fs laser pulse. The result showed that the transition energy from the 1Q x states, consisting of 1Q x (1,0) (π, π *) state (existing at 18800 cm -1) and 1Q x (0,0 (π, π *) 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 1Q x (0,0) ( π, π *) → 3 (d, π *) in the five-coordinate Ru II (TPP) (CO) in the solution was found to take place in about 1 ps.
