Abstract
Fluorescence excitation and emission spectra of the S1 and S2 states of model trienes and tetraenes are measured in free jet expansions. The barriers to cis-trans isomerization in the S1 state are < 200 cm-1 for trienes and approximately 2000 cm-1 for tetraenes. < 250 fs nonradiative decay of the S2 state of tetraenes is deduced from the observed Lorentzian linewidths.
