Using the infrared-absorption technique of surface-electromagnetic-wave spectroscopy (SEWS) we have studied the effects of H2 and D2 chemisorption on the SEW attenuation coefficient α in the 10-μm region between 165 and 350 K. The change in α at room temperature has also been measured for N2, O2, and CO adsorption. The coverage (CTHETA) dependence of α for N2, O2, and CO is fairly simple [either a monotonic increase (N2) or a peak at some intermediate coverage (O2, CO)] and points to changes in free-carrier (FC) surface …
