Abstract

Time-resolved spectroscopic experiments on Zn^II porphyrins were carried out. Photoinduced vibrational coherent motions on the electronically ground and excited states of two Zn^II porphyrins in toluene were studied impulsively using chirp-controlled femtosecond pulses; Zn^IITPP, and Zn^IIOEP which are representative porphyrin monomers (meso- versus β-substituted). In both porphyrins, it was observed that the S₂ state dynamics are much different from each other.
