Structural study on excited state proton transfer reactions mechanism utilizing an intense mid-infrared laser

该项目研究了在超音速射流膨胀中产生的1-萘酚-氨团簇的激发态质子转移反应的机理，利用新开发的中红外激光系统在ZnGeP 2晶体中使用差频产生实现的5-12微米区域的中红外光谱。通过对簇形成条件的优化，我们能够获得更高质量的光谱。在n=5时，由红外光谱确定了质子转移的阈值大小，并进行了理论计算。这些结果将有助于发展结构可靠的反应机理研究激发态反应使用气相溶剂化团簇。

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.
