The book provides an up-to-date overview of the fast growing area of Raman spectroscopy.The two-volume work describes how analytic methods using Raman spectroscopy allow for the chemical analysis of materials, providing even spatial resolution without precedent. In addition, external perturbations (strain, temperature, pressure) on molecules and their alignment can be analyzed. Raman spectroscopy can also provide information about the interactions of components, again at a high level of spatial resolution. In the form of tip-enhanced Raman spectroscopy (TERS), the method is a valuable tool for nanotechnology. This book is intended for researchers or lecturers in chemistry and materials science, who are interested in the composition and properties of their samples. It describes how Raman spectroscopy will enable them to examine thin layers, surfaces, and interfaces and improve their knowledge about the properties of composites. In addition, it can serve as a short introduction to vibrational spectroscopy.
