The fluorescence spectra and intrinsic lifetimes of two constrained trienes [cholesta-4,6,8(14)-triene and cholesta-5,7,9(11)-triene-3β-01] indicate that the lowest energy singlet-singlet transition of the s-trans,cis,s-trans 4,6,8(14) triene is a weak transition to a 1Ag-like excited state while the s-cis,trans,s-cis 5,7,9(11) triene has a lowest transition which is strongly allowed to a 1Bu-like excited state.
