Here, we present rotational constants for the 1:1 acid-base cluster in both $S_{0}$ and $S_{1}$, which provide the location of water within the cluster, as well as the barrier height to internal rotation of water in each electronic state. The barrier height decreases slightly upon excitation, from 206 \wn in $S_{0}$, to 182 \wn in $S_{1}$. There is also little evidence of a large change in water location, orientation, or overall hydrogen bond length upon irradiation with UV light. Thus, a single water molecule has relatively little affect on the substrate photo-acidity measured in the liquid phase. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title INTERNAL DYNAMICS OF WATER ATTACHED TO A PHOTOACIDIC SUBSTRATE: HIGH RESOLUTION ELECTRONIC SPECTROSCOPY OF $\beta$-NAPHTHOL-WATER IN THE GAS PHASE en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
