Vibronic coupling in polyenes: High resolution optical spectroscopy of a simple Schiff base

Article abstract of DOI:10.1063/1.447003

High resolution fluorescence and fluorescence excitation spectra of a model polyene Schifl' base have been obtained. 4.2 K spectra of N-(2, 4, 6, 8,10-dodecapentaenylidine)butyl amine in n- tetradecane exhibit well-resolved electronic spectra (??^*) from a single mixed crystal site.The major vibronic features, in common with those of polyene hydrocarbons, are due to combinations of symmetric carbon-carbon stretching vibrations.These are dominated by a double bond mode which decreases from 1589 to 1544 cm^-1 upon electronic excitation.This decrease contrasts the 15 - 200 cm^-1 increases seen in analogous polyene hydrocarbons.This diflerence is discussed in terms of vibronic coupling in a model previously applied to the hydrocarbons.
