Excited-state proton transfer in 2-(2'-hydroxyphenyl)benzothiaxole (HBT) dissolved in pyridine is investigated. New absorptions and fluorescence bands are detected after addition of water or NaOH to the solution. The spectra are identical to the HBT anion absorption and fluorescence. Picosecond spec
