This book highlights recent advances and evolution of various nanomaterials and their potential in diverse research fields.

The book highlights recent developments in the field of spectroscopy by providing the readers with an updated and high-level of overview. The focus of this book is on the introduction to concepts of modern spectroscopic techniques, recent technological innovations in this field, and current examples of applications to molecules and materials relevant for academia and industry. The book will be beneficial to researchers from various branches of science and technology, and is intended to point them to modern techniques, which might be useful for their specific problems. Spectroscopic techniques, that are discussed include, UV-Visible absorption spectroscopy, XPS, Raman spectroscopy, SERS, TERS, CARS, IR absorption spectroscopy, SFG, LIBS, Quantum cascade laser (QCL) spectroscopy, fluorescence spectroscopy, ellipsometry, cavity-enhanced absorption spectroscopy, such as cavity ring-down spectroscopy (CRDS) and evanescent wave-CRDS both in gas and condensed phases, time-resolved spectroscopy etc. Applications introduced in the different chapters demonstrates the usefulness of the spectroscopic techniques for the characterization of fundamental properties of molecules, e.g. in connection with environmental impact, bio-activity, or usefulness for pharmaceutical drugs, and materials important e.g. for nano-science, nuclear chemistry, or bio-applications. The book presents how spectroscopic techniques can help to better understand substances, which have also great impact on questions of social and economic relevance (environment, alternative energy, etc.).

This book highlights recent advances of spectroscopic techniques based on Raman scattering. Different applications are introduced that serve as examples for the versatile use of Raman techniques. Raman spectroscopy is a marker free technique, which is capable of yielding detailed information about molecular systems in a non-destructive way. This makes it a valuable tool for, e.g., material science or medical research. The access to vibrational energy and dynamics yields fundamental insights into static and dynamical structural properties of molecules being influenced by and influencing their material science or medical research environment. The better understanding of the basic building blocks of materials helps to improve the functionality in various applications. Raman spectroscopy has become a truly interdisciplinary research tool, and the ongoing development of techniques makes it attractive for growing variety of scientific and industrial applications, which will be demonstrated in the book. While the “classical” linear spontaneous Raman spectroscopy is restricted in its applicability due to low signal intensities or the excitation of strong fluorescence background, new techniques have helped to overcome such problems. Examples, presented in the book, are surface-enhanced Raman scattering (SERS), and various associated techniques are used to drastically increase signal intensity, confocal, and tip-enhanced Raman scattering (TERS) allowing for high and even sub-diffraction limited spatial resolutions, coherent anti-Stokes Raman scattering (CARS) avoiding fluorescence background and allowing for time-resolved observations of vibrational dynamics, or hyper- and resonance Raman scattering influencing the scattering based on electronic resonances, etc.
