概要 The relation between the vibronic coupling strength of the vibronic state combined with the optical transitions with short pulses and the symmetry of the coupled vibrational modes was studied by vibrational real-time spectroscopy. A pump-probe experiment of thiophene oligomers was performed using 6.7 fs pulsed laser. The vibronic coupling in both the ground and excited states was classified into two types: the displaced (D) type with D potential surfaces and the non-displaced (ND) type with ND potential surfaces between the two electronic studies. The D and ND types were found to be related to inversion anti-symmetric and symmetric molecular vibrations, respectively, with respect to the center of the pseudo-inversion symmetry of the molecule. The symmetry center is located at the middle point of the bond connecting the two quinoid-type thiophene rings.
