Usin excited state absorption decay experiments (ESA), time-resolved fluorescence and stimulated emission measurements, we have further investigated the photophysics of the barrierless isomerization of the molecule l,l'diethyl-4,4'-cyanine. The observed fluorescence lifetimes are strongly wavelength
The dynamic behavior of the second excited singlet state of QCS has been investigated for the first time in liquid solutions. In perfluoroalkane solvents strong B-ji. fluorescence (@f up to 0.077) 1s observed when the molecule is excited to bound vibrational states. s lifetimes of up 10 2.8 ns are o
