"The sub-ps lifetime of the 2A state on Z-hexatriene as deduced from its transient absorption spectrum" S. Lochbrunner, W. Fuß, K.-L. Kompa, W. E. SchmidChem. Phys. Lett. 274 (1997), 491-498 Abstract: Exciting Z-hexatriene in ethanol at its UV absorption band (1B<->2) gives rise to two types of transient absorption. Below 325 nm the time constants depend on the wavelength; they can be assigned to ground-state processes such as cooling. The hot ground state forms within 470 fs as determined from the wavelength-independent decay of the absorption between 325 and 450 nm. This absorption starts from the lowest excited state 2A . This state undergoes internal conversion and Z to E isomerization. The 2A absorption is clearly different from the 2A spectrum of the E isomer. The Z to E and E to Z isomerizations thus do not have a common intermediate.
