| 601 |  | Vardeny, Zeev Valentine; Ehrenfreund, Eitan A. | Apparent phonon side-band modes in π-conjugated systems: polymers, oligomers and crystals | The emission spectra of many π-conjugated polymers and oligomers contain side-band replicas with apparent frequencies that do not match the Raman active mode frequencies. Using a time dependent model we show that in such many mode systems, the increased damping of the time dependent transition dipo... | 2005-11 | |
