Euclted-slate proIon translcr in 2.(2'.hydroxypbenyl)benzovazole (PBX-OH) was quntltatively stuched using model compounds PBX and PBX-OCH3. Low tempcrnturc ils well OS OH 4 OD substitution slow proton transfer. No isolopc clfeet on tutomcrx fluorescence or prunnry phosphorescence hfetimcs IS observed. Proton transfer in excltcd PBX-OH OCCUIS from the .SI stitc with wry low actlmtlon energy.

The "double" derivatives of benzoxazole, bis-&S-(2-benzoxaroiyl)hydroquinone (II) and bis-3,6-(2-benzosazolyl)pyrocatochol (III), have been investigated. In (II), ordy one proton is transferred in the Sr state. Primary and tautomeric forms exist in a rapidly established equilibrium. In (III), two ta

Molecular orbital calculations reveal that the keto tautomer of HOCHCHNHNCHz, unlike the enol, does not represent a minimum in the ground state proton transfer potential. Excitation to the first excited singlet or triplet state leads to a rapid and barrierless transfer to the keto which becomes stro

Picosecond kinetics of excited-state single-or double-proton transfer along intramolecular hydrogen bonds were analyzed for three molecules: 2,5-his-( 2-benzoxazolyl )hydroquinone, its monomethoxy-derivative and 3,6-bis-(bbenzoxazolyl)pyrocatechol. Forward and back proton-transfer rate constants wer
