Chemists develop an understanding of chemical reactions and materials by making measurements using several types of instrument. Each technique gives some information and insight; and, when all of this is put together, a coherent picture may emerge. However, one fascinating area of chemistry is almost impossible to study using some of the most powerful techniques in chemistry. These systems are single molecular layers on low surface area solids. Low surface area samples yield very little signal in XRD or NMR experiments, making them extremely hard to characterise. Hence, characterisation relies heavily on infrared spectroscopy measurements. Funding is requested for a highly sensitive and stable FTIR spectrometer, so as to study selective catalytic reactions on metal surfaces.

化学家通过使用几种类型的仪器进行测量来了解化学反应和材料。每种技术都提供了一些信息和见解;当所有这些放在一起时，一幅连贯的画面可能会出现。然而，化学的一个迷人的领域几乎不可能使用化学中一些最强大的技术来研究。这些系统是在低表面积固体上的单分子层。低表面积的样品在XRD或NMR实验中产生的信号非常小，使得它们非常难以分离。因此，表征在很大程度上依赖于红外光谱测量。要求为一台高灵敏度和稳定的傅里叶变换红外光谱仪提供资金，以便研究金属表面的选择性催化反应。
