Investigation of Photochemistry in Surface Adsorded Metal Carbonyl Compounds Using FTIR and Infrared Laser Spectroscopy

这些初步研究的主要目的是证明全内反射红外技术在研究表面吸附的金属羰基化合物方面是高度敏感和有用的。这些研究也将有助于理解铬(CO)6在氧化铝表面的红外光谱，从而为拟议的研究提供背景。可以确定铬(CO)6与表面以及与其他铬(CO)6分子的相互作用，并可以阐明表面吸附分子的结构。研究人员将在这段计划期间准备一份研究提案，该提案将证明拟议的实验技术的可行性，以及这些实验在主要是本科生的机构进行的能力。很大一部分时间将用于获取初步数据。测量了吸附在Al_2O_3单晶表面上的Cr(CO)_6的红外吸收光谱随表面覆盖度的变化。这些测量将证明拟议研究的可行性以及该机构的能力。

The primary purpose of these initial studies is to demonstrate that total internal reflection infrared techniques are highly sensitive and useful in the study of surface adsorbed metal carbonyl compounds. These studies will also form a background for the proposed research by aiding in the understanding of the infrared spectra of Cr(CO)6 on Al2O3 surfaces. The interactions of Cr(CO)6 with the surface and with other Cr(CO)6 molecules can be determined, and the structure of the surface adsorbed molecule can be elucidated. The investigator will spend this planning period preparing a research proposal that will demonstrate the feasibility of the proposed experimental techniques, and the ability for these experiments to be carried out at a primarily undergraduate institution. A significant portion of the time will be utilized obtaining preliminary data. The infrared absorption spectrum of Cr(CO)6 adsorbed on Al2O3 single crystal surfaces will be measured as a function of surface coverage. These measurements will demonstrate the viability of the proposed research as well as the capability of the institution.
