Abstract
The linear electron-phonon interaction in dye-doped polymers has been investigated with Fourier-transform spectroscopy based on femtosecond accumulated photon echo [1]. This technique enables us to extract the homogeneous spectrum from the inhomogeneously broadened absorption spectrum. The obtained homogeneous spectrum, in particular, the phonon sideband spectrum and its temperature dependent variation has been analyzed according to the theory which takes into account the linear electron-phonon interaction [2,3]. The relation between the phonon sideband spectrum and the low-frequency Raman spectrum of the host polymer has also been discussed from fracton picture [4].
