Solvent assisted excited state proton transfer in indigo carmine investigated by two-dimensional electronic-vibrational spectroscopy

Conference ·
; ; ; ; ; ;
The solvent dependent electronic excited state deactivation dynamics of Indigo Carmine is mapped by the two-dimensional electronic-vibrational spectroscopy (2DEV). The H-bonding ability of the solvent has been found to assist the excited state proton transfer.
