"Proton transfer and internal conversion of o-hydroxybenzaldyde: Coherent versus statistical excited state
dynamics" K. Stock, T. Bizjak, and S. LochbrunnerChem. Phys. Lett. 354 (2002), 409-416 Abstract: The intramolecular excited state proton transfer (ESIPT) and internal conversion (IC) of o-hydroxybenzaldehyde was investigated by transient absorption measurements with 30 fs time resolution and quantitative fluorescence spectroscopy. A 45 fs delayed rise of the product emission and coherently excited vibrations indicate that the ESIPT is a ballistic motion of a well defined wavepacket along skeletal coordinates of the H- chelate ring. The IC proceeds as thermally activated process over an energy barrier of about 200 meV caused by an avoided crossing between the BMO authors (in alphabetic order): Tanja Bizjak Stefan Lochbrunner Kai Stock Order Hardcopy  WWW-Version |
