“…2 a, b, is that the frequency or potential dependence of (l/R;) (d2Rp/dp2) decreases much more smoothly from the maximum corresponding to the photoemission threshold than predicted by the theory. Special analysis has shown that this difference cannot be eliminated altogether [13] even if the finiteness of electron temperature is taken into account. It is, therefore, natural to assume that this phenomenon has its origin in many-particle effects, the influence of which is significant especially near the threshold.…”

A theory is developed to explain the electroreflectance (ER) of metals in a light energy interval near the photoemission threshold under the assumption that the microscopic mechanism of electromodulation is caused by the dependence of the external photoemission threshold on the field applied. Expressions for electroreflectance are derived containing parameters which depend on the electron structure of surface. The theory is compared with the experiment.

“…Thus, it was found that 6, + y = -go", 6, + y = Interestingly, when the electrolyte composition is changed, so do the surface properties, and accordingly the phase changes, too. For instance, when the electrolyte concentration was increased to 0.1 N, the phase 6, + y changed by 15" [6]. Thus, our experiment is a sensitive method of determining the electron characteristics of a surface.…”

The dependences of one-and two-photon photoemission currents from metal on angle of incidence and polarization of light are considered. They are found to be affected by the electric field intensity near the metal boundary. Unlike previous expressions for photocurrent, the formula derived includes an interference term between the amplitudes of probability of transition under the action of fields normal and parallel to the boundary. Experimental data on photoemission and electroreflectance of lead and indium are analyzed. Such a combined analysis may reveal certain essential electronic characteristics of the boundary, in particular, change in the phase of reflection of electrons on Fermi surface from the metal surface when its state changes. The effect of microroughness of the metal boundary on frequency and polarization dependences of photoemission is given special attention. The most significant effects arise in a frequency range where surface plasmons are created. The theory is consistent with experiments on photoemission from silver. OT

A review of ultravioletlvisible, infra-red and Raman spectroscopic techniques (excluding ellipsometry), applied to the in sttu characterization of immersed electrodes is presented. Literature reports involving transmission and internal reflectance at optically transparent electrodes, and also external specular reflectance at planar electrodes both in the visible and in the infra-red spectral regions are described. Raman techniques covered include not only recent developments in surface-enhanced Raman scattering but also unenhanced Raman scattering, resonance Raman scattering and other non-linear processes. Specialized instrumentation requirements are discussed and experimental methodology relevant to the characterization of electrochemical systems is outlined. The report concludes by highlighting the advantages and limitations of the various in siru spectroscopic techniques indicating likely areas of development in the future.
