Abstract
The initial proton transfer dynamics of 4-hydroxy-1-naphthalenesulphon ate has been studied in alcohol-water (7:3) mixtures at room temperatu re by using picosecond time-resolved emission spectroscopy. Consecutiv e processes of dissociation, recombination, re-dissociation have been observed in methanol-water and ethanol-water mixtures. However, no rec ombination has been found in the 1-propanol-water mixture. The need fo r a particular solvent structure for the proton hydration is discussed .
