Abstract

AM1 and INDO/SDCI calcns. have been performed on a excited-state intramol. proton transfer reaction of bis-2,5-(2-benzoxazolyl)hydroquinone (I). The results of potential energy surface, barrier, and transition state for the title reaction have been obtained. The calculated excited-state spectra yield a consistent interpretation of data from experimental observations. Finally, the reaction mechanism has been suggested, it is shown that only single proton transfer takes place rather than double proton transfer does.

Key words: REACTION MECHANISM, EXCITED STATE, INDENE P, POTENTIAL BARRIER, POTENTIAL ENERGY SURFACE, INTERMEDIATE NEGLECT OF DIFFERENTIAL OVERLAP APPROXIMATION (IND, HYDROQUINONE, TRANSITION STATE
