By simulating the effect of temperature on the absorption spectra of Ag and Cu (110), we show the differing importance of the various processes influencing the temperature dependence of the width and intensity of the 1.7 eV Ag (110) reflection anisotropy spectroscopy (RAS) peak and the surface state contribution to the Cu (110) 2.1 eV RAS peak. Our results show that the significance of these processes in each case is governed by the energy gap between the associated occupied surface state involved and the Fermi energy.
