Fourier-Transform Infrared Spectrometer for Infrared Reflection-Absorption Spectroscopy (IRAS)

获得了傅里叶变换红外光谱仪，为工程研究提供了支持。该仪器将与现有的超高真空系统一起用于红外反射吸收光谱(IRAS)。最初，它被用来研究定义良好的单晶金属氧化物表面上的吸附，并探索这些表面上吸附和催化反应的局部位置要求。正在研究的具体体系包括氧化亚铜上的简单分子，以及氧化亚铜、氧化锡和氧化铬上的各种氧化反应。这些努力的潜在应用包括商品化学品、特种化学品、电子材料和污染控制。

A Fourier-transform infrared spectrometer is acquired to support research in engineering. The instrument is to be used in conjunction with existing ultrahigh-vacuum systems for infrared reflection-absorption spectroscopy (IRAS). Initially, it is used to study adsorbates on well-defined, single-crystal, metal-oxide surfaces and to probe the local site requirements for adsorption and catalytic reactions on such surfaces. Specific systems under investigation include simple molecules on cuprous oxide, and a variety of oxidations over cuprous oxide, stannic oxide, and chromous oxide. Potential applications from these efforts exist in commodity chemicals, specialty chemicals, electronic materials, and pollution control.
