The electronic spedm of a merocyanine dye in a polar &vent have been studied at different temperatures. Absence of excitation wavelength dependence at room temperature in a fluid medium isdue to orientational and translational relaxation of the "solvent-cage". For the rigid solution, Uetimesof vario

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
Fluorescence lifetime measurements of purified 7-azaindole in methanol and butanol as a function of temperature are performed. The results indicate that in alcohols there exists a population of 'I-azaindole that is solvated in such a way that excitedstate tautomerixation is no longer a viable mode o
