摘要: Excited-state dynamics and mechanisms of the rapid deactivation process indigo carmine (InC) were investigated by means femtosecond transient absorption spectroscopy steady-state Raman spectroscopy. Solvent dependence excited-state lifetime revealed that intermolecular hydrogen-bonding with solvent molecule is more effective than intramolecular ones to accelerate process. Steady-state spectra in low-frequency region indicated a loss molecular planarity protic solvents. It was concluded excited state, which leads twisting around central CC bond and/or out-of-plane deformation, crucial importance deactivation.
