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.

本课题利用新研制的中红外激光系统在ZnGeP2晶体中利用差频产生技术实现5-12微米区域的中红外光谱，研究了超音速射流膨胀产生的1-萘酚-氨团簇的激发态质子转移反应机理。通过对星团形成条件的精细优化，可以获得更高质量的光谱。通过理论计算，从红外光谱中确定了n=5时质子转移的阈值大小。这些结果将有助于发展结构可靠的气相溶剂化团簇激发态反应机理研究。
