This second edition provides a cutting-edge overview of physical, technical and scientific aspects related to the widely used analytical method of confocal Raman microscopy. The book includes expanded background information and adds insights into how confocal Raman microscopy, especially 3D Raman imaging, can be integrated with other methods to produce a variety of correlative microscopy combinations. The benefits are then demonstrated and supported by numerous examples from the fields of materials science, 2D materials, the life sciences, pharmaceutical research and development, as well as the geosciences.

Infrared and Raman Spectroscopy, Principles and Spectral Interpretation, Second Edition provides a solid introduction to vibrational spectroscopy with an emphasis on developing critical interpretation skills. This book fully integrates the use of both IR and Raman spectroscopy as spectral interpretation tools, enabling the user to utilize the strength of both techniques while also recognizing their weaknesses. This second edition more than doubles the amount of interpreted IR and Raman spectra standards and spectral unknowns. The chapter on characteristic group frequencies is expanded to include increased discussions of sulphur and phosphorus organics, aromatic and heteroaromatics as well as inorganic compounds. New topics include a discussion of crystal lattice vibrations (low frequency/THz), confocal Raman microscopy, spatial resolution in IR and Raman microscopy, as well as criteria for selecting Raman excitation wavelengths. These additions accommodate the growing use of vibrational spectroscopy for process analytical monitoring, nanomaterial investigations, and structural and identity determinations to an increasing user base in both industry and academia. Integrates discussion of IR and Raman spectra Pairs generalized IR and Raman spectra of functional groups with tables and text Includes over 150 fully interpreted, high quality IR and Raman reference spectra Contains fifty-four unknown IR and Raman spectra, with a corresponding answer key

Raman microscopy is now well-established as one of the most powerful and versatile techniques for a diverse range of applications in both research and analytical laboratories. Its unique advantage is its ability to noninvasively characterize chemically complex and spatially inhomogeneous samples with a sub-micron spatial resolution. Modern confocal Raman scanning microscopy, which allows one to obtain two- and three-dimensional spectrochemical images of samples in various states and forms, has become a method of choice for a wide range of applications including the study of biological cells, tissues, and microorganisms, characterization of pharmaceutical drugs and formulations, forensic evidence, minerals and gems, carbon nanomaterials, semiconductors, composite polymers, and more. This book presents the techniques of confocal Raman microscopy and imaging for researchers and engineers from a variety of disciplines. It highlights the key aspects of this technique in order to effectively apply it in practice. It will appeal to a wide circle of readers who are interested in, or are already, using the methods of confocal Raman microscopy and imaging in their work, and will also be beneficial for novice Raman microscopy users.

Raman imaging has long been used to probe the chemical nature of a sample, providing information on molecular orientation, symmetry and structure with sub-micron spatial resolution. Recent technical developments have pushed the limits of micro-Raman microscopy, enabling the acquisition of Raman spectra with unprecedented speed, and opening a pathway to fast chemical imaging for many applications from material science and semiconductors to pharmaceutical drug development and cell biology, and even art and forensic science. The promise of tip-enhanced raman spectroscopy (TERS) and near-field techniques is pushing the envelope even further by breaking the limit of diffraction and enabling nano-Raman microscopy.

Raman spectroscopy is now well established as one of the most versatile techniques for the chemical analysis of molecular species. Major advances have been made in a number of areas in the field in recent years which enable the researcher and practising analytical scientist to solve the complex chemical problems of today. The ten chapters in Modern Techniques in Raman Spectroscopy cover some of the most exciting fields of research in modern Raman techniques, and illustrate the power of modern Raman spectroscopy for molecular analysis in both theoretical and practical problems. The volume opens with chapters on signal expressions and instrumentation in Raman spectroscopy, and then goes on to discuss in detail Fourier and Hadamard Transform Raman spectroscopies, micro-Raman spectroscopy, surface-enhanced Raman spectroscopy, Raman optical activity, coherent and time-resolved techniques and the use of optical fibres in Raman spectroscopy. The chapters are written by leading researchers from a broad range of disciplines. Throughout, applications of the various techniques are discussed. Modern Techniques in Raman Spectroscopy will be of great interest to all those involved in molecular spectroscopy, in both industry and academia. The inclusion of a wide range of modern techniques in a single volume will make this a particularly valuable work to researchers across the whole field of Raman spectroscopy.

This dissertation focuses on the application of Tip-Enhanced Raman spectroscopy (TERS) to non-transparent and non-conductive samples, allowing for the optical characterization of nanoelectronic devices. As such, nano-crystals are analyzed as a model system for the investigation of chemical and structural properties. Furthermore, a novel method for mapping the refractive index of materials with nanometer resolution is presented. The technological progress of electronics through miniaturization has reached the nanoscale while new materials with high performance and functional properties gain importance. Quality control and the scientific understanding of size effects in electronic nanostructures are required more than ever to consolidate existing technologies and to determine scaling limits of new materials. Conventional techniques, including scanning electron and scanning probe microscopy, provide topographic information but only very limited chemical information to analyze the physical properties of nanomaterials. Chemical and structural sensitivity is available by Raman or infrared spectroscopy, but with a spatial resolution limited to the microscale by the diffraction limit of light. TERS combines the virtues of scanning probe microscopy with those of optical spectroscopy to overcome the diffraction limit through the excitation of surface plasmons on a scanning probe tip to confine light to nanometers. In this work, a TERS system was installed to operate on opaque samples by employing optical side access. TERS probes were fabricated by electrochemical etching and operated in scanning tunneling microscopy and atomic force microscopy with quartz tuning forks to enable scanning on various surfaces. TERS was then applied to ferroelectric lead titanate nano-crystals on a platinized silicon substrate as a model system for nanostructured, charge-based memory devices at the onset of finite size effects.

Raman spectroscopy has been known and used as a technique for 80 years, originally for the study of inorganic substances. Recent advances in underlying technology, such as lasers, detectors, filters and components, have transformed the technique into a very effective modern tool for studying complex biological problems. Professor Mahmoud Ghomi (of the University of Paris XIII) has edited this book on the applications of Raman spectroscopy to biology, covering in a readily accessible way the area from basic studies to the diagnosis of disease. The early chapters provide background information on basic principles underlying the main Raman methods covered in the book, with information on Surface-Enhanced Raman Scattering (SERS) and Surface-Enhanced Fluorescence (SEF), as well as giving accounts of applications to biomolecular and cellular investigations. Among the topics covered are studies of drugs and their complexes with biomolecules on nanoparticles, application of SERS to blood analysis, studies of single cells and of applications to human cancer diagnostics.This will be a useful book for experimental scientists in academic, governmental, industrial and clinical environments and for those entering the field of biomolecular spectroscopy.
