Abstract
A compact vacuum cell and associated optics used to obtain a single‐reflection infrared spectrum of a thin film on a metal surface is described. Reflection‐absorption spectroscopy, in the past, has usually involved multiple reflections. Single reflection setups offer advantages of simplicity, the ability to generate and/or clean the sample surface, and the ability to use other surface studies techniques along with ir. An optical setup is described which will allow the above three advantages to be obtained, and in addition is simple and compact. Along with the optics, a vacuum cell housing the sample is described. This cell fits conveniently with a standard infrared spectrometer and no additional modification to the spectrometer is required.
