Apparent phonon side band modes in pi-conjugated systems: polymers, oligomers and crystals
E. Ehrenfreund, C. C. Wu, Z. V. Vardeny
The emission spectra of many pi-conjugated polymers and oligomers contain side-band replicas with apparent frequencies that do not match the Raman active mode frequencies. Using a…

Apparent vibrational side-bands in pi-conjugated systems: the case of distyrylbenzene
C. C. Wu, E. Ehrenfreund, J. J. Gutierrez +2
The photoluminescence (PL) spectra of dilute solution and single crystals of distyrylbenzene show unique temperature dependent vibronic structures. The characteristic single freque…
