| Research Abstract |
This project studied mechanism of the excited state proton transfer reaction of 1-naphthol–ammonia clusters produced in a supersonic jet expansion utilizing mid-infrared spectroscopy in the 5-12 micrometer region realized by newly developed mid-infrared laser system using difference frequency generation in ZnGeP2 crystals. Fine optimization of the cluster formation condition was able us to record higher quality spectra. The threshold size of the proton transfer was determined at n=5 from the infrared spectra with a help of theoretical calculations. These results will contribute development of structurally reliable reaction mechanism study on excited state reactions using gas phase solvated clusters.
