SERS was discovered in the 1970s and has since grown enormously in breadth, depth, and understanding. One of the major characteristics of SERS is its interdisciplinary nature: it lies at the boundary between physics, chemistry, colloid science, plasmonics, nanotechnology, and biology. By their very nature, it is impossible to find a textbook that will summarize the principles needed for SERS of these rather dissimilar and disconnected topics. Although a basic understanding of these topics is necessary for research projects in SERS with all its many aspects and applications, they are seldom touched upon as a coherent unit during most undergraduate studies in physics or chemistry. This book intends to fill this existing gap in the literature. It provides an overview of the underlying principles of SERS, from the fundamental understanding of the effect to its potential applications. It is aimed primarily at newcomers to the field, graduate students, researchers or scientists, attracted by the many applications of SERS and plasmonics or its basic science. The emphasis is on concepts and background material for SERS, such as Raman spectroscopy, the physics of plasmons, or colloid science, all of them introduced within the context of SERS, and from where the more specialized literature can be followed. - Represents one of very few books fully dedicated to the topic of surface-enhanced Raman spectroscopy (SERS) - Gives a comprehensive summary of the underlying physical concepts around SERS - Provides a detailed analysis of plasmons and plasmonics

Given the inherent complexity of food products, most instrumental techniques employed for quality and authenticity evaluation (e.g., chromatographic methods) are time demanding, expensive, and involve a considerable amount of manual labor. Therefore, there has been an increasing interest in simpler, faster, and reliable analytical methods for assessing food quality attributes. Spectroscopic Methods in Food Analysis presents the basic concepts of spectroscopic methods, together with a discussion on the most important applications in food analysis. The determination of product quality and authenticity and the detection of adulteration are major issues in the food industry, causing concern among consumers and special attention among food manufacturers. As such, this book explains why spectroscopic methods have been extensively employed to the analysis of food products as they often require minimal or no sample preparation, provide rapid and on-line analysis, and have the potential to run multiple tests on a single sample (i.e., non-destructive). This book consists of concepts related to food quality and authenticity, that are quite broad, given the different demands of the manufacturer, the consumer, the surveillance and the legislative bodies that ultimately provide healthy and safe products.

The most amazing field of modern inorganic chemistry is co-ordination chemistry. From last four decades, co-ordination chemistry created its own identity in the Inorganic chemistry. The co-ordinate compounds also referred as complexes is a combination of ligand or chelating agent with metal ions through co-ordinate bonds. Ligands are covalent bonded organic molecules containing lone pair or lone pairs of electrons on heteroatom in the organic moiety. As metal ions are electron deficient so these form co-ordinate bonding between metal ion and ligand. The behaviour of metal ion with different ligands depends upon the sterric hindrance, structure, various substituent and nature of bonding present in ligands as well as screening effect, Kernal effect, atomic number oxidation state of metal ion. It was also observed in complexes that there are primary as well as secondary valencies.

The field of nanoscience has undergone tremendous growth in the past decade as the number of applications of nanoparticles and nanostructured materials have proliferated. Metal nanoparticles have attracted particular interest due to their potential for applications in areas as diverse as catalysis, medicine and opto-electronics. The chemical and physical properties of metal nanoparticles can vary smoothly or discontinuously with nanoparticle size, depending on the size regime and the property. In the case of bi- or multimetallic nanoparticles ("nanoalloys"), these properties also depend on the elemental composition and the chemical ordering - how the metals are distributed in the nanoparticles.It is this tunability of behavior that makes metal nanoparticles and nanoalloys so versatile and appealing. This book begins with a tutorial introducing the theoretical ideas and models that have been developed to understand metal nanoparticles. It gives an overview of experimental methods for generating and characterizing metal nanoparticles and nanoalloys and of their properties and applications, providing an introduction to material covered in more depth in subsequent chapters. A major theme of all the chapters is the effect of nanoparticle size, shape and surface chemistry on their properties - especially optical and catalytic properties. A unified discussion of the inter-relations between modelling, synthesis and physical properties of nanoparticles and nanoalloys A discussion of the most promising new catalytic and photocatalytic applications of nanoparticles and the approaches used to achieve these goals A tutorial introduction which provides a basis for understanding the subsequent specialized chapters

This primer is geared toward undergraduate and graduate students who possess a basic understanding of chemistry and physics and are looking for a route to enter the world of electron energy loss spectroscopy (EELS). It may also be a convenient reference for established researchers interested in adopting a new analytical method or simply for anyone eager to learn more about electron–matter interactions. This primer is divided into five chapters to guide your reading: Chapter 1 introduces the concept of electron-based spectroscopy and defines what qualifies as an electron-based technique. The authors outline the principal interactions at play and present a range of methods that correspond to different types of signals. The chapter concludes with a concise historical narrative tracing the development of EELS. Chapter 2 details the background required to build a deeper understanding of EELS and spectroscopy. The authors connect photon-based and electron-based approaches, highlighting where they overlap and where they diverge. Chapter 3 focuses on the fundamental instrumentation used in electron spectroscopy, discusses optimization strategies, and introduces key instrument parameters. The authors compare different electron sources, optical geometries, and lens configurations. Chapter 4 explores scattering mechanisms and electron–matter interactions, offering theoretical underpinnings and guidance on interpreting EELS spectra. Key concepts such as elastic and inelastic scattering, core-level transitions, plasmons, and analysis methods are reviewed. Chapter 5 concludes with real-world applications, such as the use of EELS in biology, nanomaterials, polymers, and solid-state systems. The authors also briefly survey emerging directions, including in situ and ultrafast EELS, underscoring the method’s evolving landscape.
