The 3rd edition of this textbook offers clear explanations of optical spectroscopic phenomena and shows how spectroscopic techniques are used in modern chemistry, biochemistry and biophysics.Topics included are: electronic and vibrational absorption fluorescence symmetry operations and normal-mode calculations electron transfer from excited moleculesenergy transferexciton interactions electronic and vibrational circular dichroismcoherence and dephasingultrafast pump-probe and photon-echo spectroscopy single-molecule and fluorescence-correlation spectroscopyRaman scatteringmultiphoton absorption quantum optics and non-linear opticsentropy changes during photoexcitationelectronic and vibrational Stark effects studies of fast processes in single moleculestwo-dimensional electronic and vibrational spectroscopyThis revised and updated edition provides expanded discussions of laser spectroscopy, crystal symmetry, birefringence, non-linear optics, solar cells and light-emitting diodes. The explanations are sufficiently thorough and detailed to be useful for researchers, graduate students and advanced undergraduates in chemistry, biochemistry and biophysics. They are based on time-dependent quantum mechanics, but are developed from first principles so that they can be understood by readers with little prior training in the field. Additional topics and highlights are presented in special boxes in the text. The book is richly illustrated with color figures throughout. Each chapter ends with a section of questions for self-examination.

This book offers a didactic introduction to light¿matter interactions at both the classical and semi-classical levels. Pursuing an approach that describes the essential physics behind the functionality of any optical element, it acquaints students with the broad areas of optics and photonics. Its rigorous, bottom-up approach to the subject, using model systems ranging from individual atoms and simple molecules to crystalline and amorphous solids, gradually builds up the reader¿s familiarity and confidence with the subject matter. Throughout the book, the detailed mathematical treatment and examples of practical applications are accompanied by problems with worked-out solutions. In short, the book provides the most essential information for any graduate or advanced undergraduate student wishing to begin their course of study in the field of photonics, or to brush up on important concepts prior to an examination.

This book illustrates the significance of various optical spectroscopy and microscopy techniques, including absorption spectroscopy, fluorescence spectroscopy, infrared spectroscopy, and Raman spectroscopy for deciphering the nature of biological molecules. The content of this book chiefly focuses on (1) the principle, theory, and instrumentation used in different optical spectroscopy techniques, and (2) the application of these techniques in exploring the nature of different biomolecules (e.g., proteins, nucleic acids, enzymes, and carbohydrates). It emphasizes the structural, conformational and dynamic, and kinetic including the changes in biomolecules under a range of conditions. In closing, the book summarizes recent advances in the field of optical spectroscopic and microscopic techniques.

This book presents commonly applied characterization techniques in material science, their brief history and origins, mechanism of operation, advantages and disadvantages, their biosensing applications, and troubleshooting for each technique, while addressing the challenges researchers face when working with these techniques. The book dedicates its focus to identifying physicochemical and electrochemical nature of materials including analyses of morphology, mass spectrometry, and topography, as well as the characterization of elemental, structural, thermal, wettability, electrochemical, and chromatography properties. Additionally, the main features and benefits of using coupled characterization techniques are discussed in this book.

This textbook is an excellent guide to microscopy for students and scientists, who use microscopy as one of their primary research and analysis tool in the laboratory. The book covers key microscopy principles and explains the various techniques such as epifluorescence microscopy, confocal/live cell imaging, SIM/light sheet microscopy, and many more. Easy-to-understand protocols provide helpful guidance for practical implementation in various commercially available imaging systems. The reader is introduced to histology and further be guided through advanced image acquisition, classification and analysis.The book is written by experienced imaging specialists from the UK, other EU countries, the US and Asia, and is based on advanced training courses for master students and PhD students. Readers are not expected to be familiar with imaging and microscopy technologies, but are introduced to the subject step by step. This textbook is indented for biomedical and medical students, as well as scientists and postdocs who want to acquire a thorough knowledge of microscopy, or gain a comprehensive overview of modern microscopy techniques used in various research laboratories and imaging facilities.Chapter 4 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

This book builds a narrative on the near-field optical and spectroscopic studies with an emphasis on plasmonic and photonic assisted nano-optics as a tool for super-lensing. Deliberations on near-field studies using confined light in various applications are included alongwith their commercial implications.

Stable Isotope Geochemistry is an introduction to the use of stable isotopes in the geosciences. For students and scientists alike the book will be a primary source of information with regard to how and where stable isotopes can be used to solve geological problems. It is subdivided into three parts: i) theoretical and experimental principles, ii) fractionation processes of light and heavy elements, iii) the natural variations of geologically important reservoirs. In the last decade, major advances in multicollector-ICP-mass-spectrometry enable the precise determination of a wide range of transition and heavy elements. Progress in analysing the rare isotopes of certain elements allows the distinction between mass-dependent and mass-independent fractionations. These major advances in analytical techniques make an extended new edition necessary. Special emphasis has been given to the growing field of "e;non-traditional"e; isotope systems. Many new references have been added, which will enable quick access to recent literature.

Dieses Buch beschreibt moderne Erkenntnisse der Farbwahrnehmung, die auf physikalischen und physiologischen Phänomenen basiert. Dargestellt werden die Vorgänge vor unserem Auge und die Umsetzung hinter unserem Auge (Gehirn). Dabei spielen Pigmente eine große Rolle bei der Manipulation der Lichtstrahlen. Diese Manipulation kann unterschiedlich sein und durch Absorption, Spiegelung oder Interferenz erfolgen. Allerdings ist es dem Auge egal, wie diese Manipulation stattfindet. Ein grünes Buntpigment erzeugt den gleichen Farbeindruck wie eine Mischung aus einem gelben und einem blauen Buntpigment. Das Buch führt populärwissenschaftlich an das Thema heran und spricht hierdurch einen großen Leserkreis an, der Interesse an naturwissenschaftlichen Themen zeigt. http://lila.wrcramer.de/
