  • The rotational dynamics of neutral and cationic forms of the phenazine dye neutral red has been studied in n-alcohols, amides, and aprotic solvents using picosecond time-resolved fluorescence depolarization spectroscopy. While both the neutral and cationic forms of neutral red experienced more or less the same friction in alcohols, the cationic form experienced 16%–26% more friction in amides and aprotic solvents exceptions being formamide and propylene carbonate (PC). The results were analyzed… CONTINUE READING
