Title Photoinduced quantum interference antiresonances in ∏-conjugated polymers
Date 2002-05
Description We observed photoinduced quantum interference antiresonances between several discrete infraredactive vibrations and the lower-polaron continuous absorption band in a series of p-conjugated polymer films having superior planar orders, where the polaron transition energy is relatively small. The photoinduced Fano-type antiresonances are well explained by extending the amplitude mode model beyond the adiabatic limit. The agreement between the data and the model confirms the presence of a continuous electronic band above the polaron state. We show that high frequency modes are strongly coupled to electrons, with implications for superconductivity.
