Abstract

Ultrafast relaxation in conjugated polymers are related with the geometrical relaxation due to electron-phonon coupling. This introduces nonlinear excitations such as solitons, polarons, and bipola- rons. In order to obtain the structural information of excited species, time-resolved (TR) vibrational spectroscopies such as TR infrared absorption, TR resonance spontaneous Raman scattering, TR resonance coherent Raman scattering (CARS) have been utilized. However, these methods have serious disadvantages such as low sensitivity, disturbance by spontaneous fluorescence, and interference with nonresonant background.
