Ultra-fast Transient Spectroscopy of ITI. a Transient absorption spectra of unsubstituted ITI 1a recorded in methanol with excitation at 400 nm. b Representative kinetic traces (open symbols) and fits obtained from target analysis (continuous line), c Time-resolved anisotropy, the initial 3 ps are shown in the inset, d Species-Associated Decay Spectra (SADS), obtained by analyzing the kinetic traces with the kinetic model depicted on the right-bottom side of the figure. The black curve represents the S1 state, the red curve hot Z isomer and the blue curve the E isomer. e Proposed model for photo-isomerization
