Collisions of vibrationally hot aromatic molecules with water that result in energy transfer and chemical reactions are investigated experimentally. Highly vibrationally excited aromatic molecules (Evib=38000 cm-1) are prepared using 266 nm excitation from a Nd:YAG laser. The appearance of individual product states of water is probed using high-resolution transient absorption at 2.7 microns from an F-center laser and 5.5 microns from a diode laser. The goal of this study is to investigate the competition between energy transfer and H/D-exchange reactions of vibrationally hot pyrazine, pyridine, and their deuterated isotopomers with H2O.
