摘要: Using sub-5fs visible laser pulses, ultrafast time-resolved absorption change was observed for Ru(II)(TPP)(CO) (TPP=5,10,15,20-tetraphenylporphirine) solved in chloroform. Exponential fitting of the time traces estimated decay life times of intermediates as 230 +/- 70 fs, 1150 +/- 260 fs, 2150 +/- 360 fs, and "4.8 ps for (1)Q(x(1,0))(pi,pi*), (1)Q(x(0,0))(pi,pi*), (3)(d, pi*), and (3)(pi, pi*), respectively. Real-time change of instantaneous molecular vibration frequency was studied by spectrogram analysis, which reflects gradual vibration mode change in the intersystem crossing from singlet state to triplet state.
