Available in PDF, EPUB and Kindle. Book excerpt: Over the past few years, there has been a growing awareness of the vibratio nal properties of solid surfaces and adsorbates due to a steady growth in the number of experimental techniques which have evolved with sufficient resolution and surface sensitivity. An understanding of the surface vibratio nal modes is of fundamental importance in many areas of the physics and chemistry of surfaces, most notably in the field of heterogeneous catalysis on metals and alloys. The present volume derives from a one day meeting of invited lectures, held under the auspices of the Thin Films and Surfaces Section of the Insti tute of Physics in the Cavendish Laboratory, University of Cambridge, 13 December 1979. The object was to bring together specialists from various diverse fields who would examine the wide variety of methods currently avail able for studying surface adsorbate vibrations. Since these methods cover several scientific disciplines, it was subsequently felt that it would be useful to provide a permanent record of the talks as a source lor future reference by workers in what is rapidly becoming an expanding field of',inter est in an increasing number of laboratories. The contributions, however, are not in any way meant to constitute exhaustive reviews.

Download or read book Encyclopedia of Chemical Physics and Physical Chemistry written by John H. Moore and published by CRC Press. This book was released on 2023-07-03 with total page 1161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Physical Chemistry and Chemical Physics introduces possibly unfamiliar areas, explains important experimental and computational techniques, and describes modern endeavors. The encyclopedia quickly provides the basics, defines the scope of each subdiscipline, and indicates where to go for a more complete and detailed explanation. Particular attention has been paid to symbols and abbreviations to make this a user-friendly encyclopedia. Care has been taken to ensure that the reading level is suitable for the trained chemist or physicist. The encyclopedia is divided in three major sections: FUNDAMENTALS: the mechanics of atoms and molecules and their interactions, the macroscopic and statistical description of systems at equilibrium, and the basic ways of treating reacting systems. The contributions in this section assume a somewhat less sophisticated audience than the two subsequent sections. At least a portion of each article inevitably covers material that might also be found in a modern, undergraduate physical chemistry text. METHODS: the instrumentation and fundamental theory employed in the major spectroscopic techniques, the experimental means for characterizing materials, the instrumentation and basic theory employed in the study of chemical kinetics, and the computational techniques used to predict the static and dynamic properties of materials. APPLICATIONS: specific topics of current interest and intensive research. For the practicing physicist or chemist, this encyclopedia is the place to start when confronted with a new problem or when the techniques of an unfamiliar area might be exploited. For a graduate student in chemistry or physics, the encyclopedia gives a synopsis of the basics and an overview of the range of activities in which physical principles are applied to chemical problems. It will lead any of these groups to the salient points of a new field as rapidly as possible and gives pointers as to where to read about the topic in more detail.
Download or read book Environmental Interfacial Spectroscopy written by Mahamud Subir and published by American Chemical Society. This book was released on 2022-04-14 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clarifying chemical processes in the environment is tantamount to creating a better and a safer planet. The chemistry that takes place within the natural world occurs not only in the bulk gaseous, liquid, and solid phases, but also in the region where two phases meet. This molecularly thin region between phases, also known as an interface, plays a significant role in various chemical processes because interfaces are ubiquitous in nature. Despite the significance of interfacial processes in environmental chemistry, investigating environmental interfaces experimentally has always been a challenge. Recent advances in nonlinear spectroscopy (NLS) have demonstrated that techniques such as sum frequency generation (SFG) and second harmonic generation (SHG) are unique in their ability to probe buried chemical interfaces. The theoretical and practical aspect of these techniques in probing environmental interfaces is the primary focus of this e-book. This e-book is geared toward curious and inquisitive minds eager to learn how molecules behave at the thin layers of chemical interfaces. A beautiful world, rich in unique insights into the interfacial environmental processes, awaits.

Download or read book Ultrafast Dynamics and Interfacial Structural Orientation Investigated with Multidimensional Vibrational Spectroscopy written by Jiaxi Wang and published by . This book was released on 2019 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, two multidimensional spectroscopic methods--two-dimensional infrared (2D IR) spectroscopy and heterodyne 2D sum frequency generation (HD 2D SFG) spectroscopy--are applied to investigate ultrafast chemical exchange of organometallics in bulk solution and structural orientation of surface catalysts at interface, respectively. 2D IR spectroscopy is used to study the ultrafast chemical exchange of two organometallics compound ( Ru(S2C2(CF3)2)(CO)(PPh3)2 and Co(CNArMes2)4 ) occurring on the picosecond time scale. Combined with DFT simulation results, 2D IR provides direct evidence of the existence of various isomers. For the five-coordinate Ru complex, one isomers that serves as the intermediate of the axial-equatorial exchange was observed for the first time. Furthermore, our 2D IR works find the kinetic barriers of dynamic exchange between multiple isomers surprisingly low, consider both of the transition metal complexes under study have relatively large ligands. The low kinetic barriers are attributed to the small core-angle movement involved in the chemical exchange. 2D IR is also applied to W(CO)6/dual cavity system to observe ultrafast intercavity nonlinear polariton interactions. Combined with a newly developed theory model, we show that the nonlinear interaction is realized by shared molecular anharmonicities among cavity modes, e.g. through mode delocalization, some molecules (with anharmonicity) are coupled by cavity modes adjacent to each other. HD 2D SFG spectroscopy is used to study a model CO2 reduction catalyst, Re(diCNbpy)(CO)3Cl, as a monolayer on a gold surface. We show that short-range interactions with the surface can cause substantial line-shape differences between vibrational bands from the same molecules. This interaction can be explained as the result of couplings between CO vibrational modes of the catalyst molecules and the image dipoles on gold surface, which are sensitive to the relative distance between the molecule and the surface. Thus, by analysis of HD 2D SFG lineshape differences and polarization dependences of IR spectra, the ensemble-averaged orientation of the molecules on the surface can be determined unambiguously. The high sensitivity of HD 2D SFG spectra to short-range interactions can be applied to many other adsorbate-substrate interactions and therefore serve as a unique tool to determine adsorbate orientations on surfaces. Meanwhile, surface molecules of the monolayers can adopt conformations with many different orientations. Thus, it is necessary to describe the orientations of surface molecular monolayers using both mean tilt angle and orientational distribution, which together we refer to as orientation heterogeneity. Orientation heterogeneity is difficult to measure. In most cases, in order to calculate the mean tilt angle, it is assumed that the orientational distribution is narrow. This assumption causes ambiguities in determining the mean tilt angle and loss of orientational distribution information, which is known as the "magic angle" challenge. Using HD 2D SFG spectroscopy, we report a novel method to solve the "magic angle" challenge, by simultaneously measuring mean tilt angle and orientational distribution of molecular monolayers. Although applied to a specific system, this method is a general way to determine the orientation heterogeneity of an ensemble-averaged molecular interface.
