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表面吸附金属羰基化合物的研究中是高度敏感和有用的。这些研究也将通过帮助理解Al2O3表面上Cr(CO)6的红外光谱，为提出的研究提供背景。可以确定Cr(CO)6与表面以及与其他Cr(CO)6分子的相互作用，并可以阐明表面吸附分子的结构。研究者将在这个计划期间准备一份研究计划，该计划将证明所提议的实验技术的可行性，以及这些实验在主要本科院校进行的能力。大部分时间将用于获取初步数据。Cr(CO)6吸附在Al2O3单晶表面的红外吸收光谱将被测量为表面覆盖的函数。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.
