Nonlinear Raman processes in polydiacetylenes
説明
In conclusion, we developed a new time resolved Raman spectroscopy and the new Raman peak due to self-trapped excitons in polydiacetylene (PDA) has been observed at 1200 cm for the first time by the femtosecond time-resolved Raman gain spectroscopy. The observed Raman signals indicate the butatriene-like structure due to the formation of the self trapped exciton (STE) after the geometrical relaxation from the acetylene-like structure in the free exciton (FE) state. >
