TL;DR: A discussion of the major methods used to measure vibrational spectra of surface species can be found in this article, where the emphasis is on basic concepts and experimental methods rather than a current survey of the extensive literature in this field.
Abstract: The observation of the vibrational spectra of adsorbed species provides one of the most incisive methods for und erst an ding chemical and physical phenomena on surfaces. At the present time, many approaches may be applied to studies of molecular vibrations on surfaces. Some of these are used on high-area solids of technological importance (e.g., heterogeneous catalysts) while others are applied to single-crystal substrates to gain better understanding under conditions of controlled surface structure. This book has attempted to bring together in one place a discussion of the major methods used to measure vibrational spectra of surface species. The emphasis is on basic concepts and experimental methods rather than a current survey of the extensive literature in this field. Two introductory chapters describe the basic theoretical aspects of vibrational spectroscopy on surfaces, dealing with normal modes and excitation mechanisms in vibrational spectroscopy. The remaining seven chapters deal with various methods employed to observe surface vibra tions. These are arranged in an order that first treats the use of various methods on surfaces that are not of the single-crystal type. It is in this area that the field first got started in the late 1940s with pioneering work by Terenin and others in the Soviet Union, and by Eisehens and others in the United States in the 1950s. The last four chapters deal with relatively recent methods that permit vibrational studies to be made on single crystal substrates."

TL;DR: In this paper, the symmetry of binding sites for adsorbed species was investigated and it was shown that electrons liberated from an adorbed layer by electron-stimulated desorption have sharply peaked, symmetric angular distributions which are in registry with the substrate.
Abstract: Ions liberated from an adsorbed layer by electron-stimulated desorption are shown to have sharply peaked, symmetric angular distributions which are in registry with the substrate. We propose a new method for investigation of the symmetry of binding sites for adsorbed species.

TL;DR: In this paper, the authors compare and discuss recent experimental and theoretical results in the field of H2O-solid interactions, and emphasize studies of low (submonolayer) coverages of water on well-characterized, single-crystal surfaces of metals, semiconductors and oxides.

TL;DR: A review of the fundamental interactions of water with solid surfaces can be found in this paper, where the authors assimilated the results of the TM review with those covered by the authors to provide a current picture of water interactions on solid surfaces, such as how water adsorbs, what are the chemical and electrostatic forces that constitute the adsorbed layer, how is water thermally or non-thermally activated and how do coadsorbates influence these properties of water.

TL;DR: Theoretical and experimental aspects of this method in a single reflection mode are discussed in this paper, where vibrational frequencies of the C-O stretch allow determination of adsorption sites.

TL;DR: In this paper, the authors discuss the possibility to use thin, well-ordered oxide films as supports for the study of deposited metal particles, which offers the advantage to permit the unrestricted application of all experimental methods, which rely on a good electrical or thermal conductivity of the sample, like PES, LEED, STM or TDS.
