Title |
Resonant Raman scattering from amplitude modes in trans-(CH)x and -(CD)x |
Date |
1983-12 |
Description |
The three resonantly enhanced Raman vibrations in trans-(CK)x and ~(CD)X are described in terms of amplitude modes associated with the Peierls gap. The dispersion in the Raman-line profiles is explained by inhomogeneity. A narrow distribution of the effective electron-phonon coupling constant is required to account for the observed spectra in detail. The resonant Raman vibrations and the ir-active modes induced by doping or photogeneration are all described by the same form of dressed phonon propagator. |
