Abstract

The reflectivity change induced by adsorbates on Cu(100) at (lambda) equals 632.8 nm is investigated. It is found that physisorbed molecules (water, methanol, acetone) induce no observable reflectivity change, while chemisorbed molecules (carbon monoxide, oxygen, acetylene) do. The magnitude of the reflectivity change is such that submonolayer sensitivity is obtained for chemisorbed species. Furthermore, the change is found to vary linearly with coverage. The results show that this technique is a versatile, inexpensive, and straightforward optical probe of the surface coverage, and as such is applicable to many different surface investigations.
