This book provides an overview of the state of the art in pharmaceutical applications of UV-VIS spectroscopy. This book presents the fundamentals for the beginner and, for the expert, discusses both qualitative and quantitative analysis problems. Several chapters focus on the determination of drugs in various matrices, the coupling of chromatographic and spectrophotometric methods, and the problems associated with the use of chemical reactions prior to spectrophotometric measurements. The final chapter provides a survey of the spectrophotometric determination of the main families of drugs, emphasizing the achievements of the last decade.

Electronic Absorption Spectra and Geometry of Organic Molecules: An Application of Molecular Orbital Theory focuses on electronic absorption spectra of organic compounds and molecules. The book begins with the discussions on molecular spectra, electronic absorption spectra of organic compounds, and practical measures of absorption intensity. The text also focuses on molecular orbital theory and group theory. Molecular state functions; fundamental postulates of quantum theory; representation of symmetry groups; and symmetry operations and symmetry groups are described. The book also discusses shape of absorption bands and geometry of excited electronic states; effect of environment on electronic absorption spectra; and the application of simple LCAO MO method to simple π systems. An evaluation of the parameters used in simple LCAO MO method is presented. The text notes the usefulness and restrictions of simple LCAO MO method in the interpretation of electronic absorption spectra. The correlation between results of simple MO calculation and spectral data in aromatic hydrocarbons, and correlation between results of simple MO calculation and spectral data in conjugated linear polyenes are discussed. The book also looks at MO methods and the relations between electronic absorption spectra and geometry of molecules, biphenyl, styrene, and related compounds. The text is a good source of data for researchers and chemistry students who want to study electronic absorption spectra.

The aim of each volume of this series Guides to Information Sources is to reduce the time which needs to be spent on patient searching and to recommend the best starting point and sources most likely to yield the desired information. The criteria for selection provide a way into a subject to those new to the field and assists in identifying major new or possibly unexplored sources to those who already have some acquaintance with it. The series attempts to achieve evaluation through a careful selection of sources and through the comments provided on those sources.

Even though the nwnber of requests for reprints and the number of quotations in the Science Citation Index has indicated an ever-increasing interest in topics of organic polarography, I have often felt that the reason that some work is less known may well be because the papers were published in less accessible journals. Therefore, I was pleased when I was asked to prepare a selection of my papers on organic polarography for reprinting. This collection of papers may indicate some of the possibilities offered by polarography in the study of properties of organic compounds. The fact that the papers are published in one volume, not only makes the information more easily accessible for the reader, but also enables a direct comparison of related topics. The mode of selection is discussed in the Introduction. The papers reprinted in this volume are mostly based on work carried out in the J. Heyrovsky Institute of Polarography of the Czechoslovak Academy of Sciences in Prague, in cooperation with my co-workers. I would like to take this opportunity of thanking all of them for the pleasure I got from this cooperation on the solution of varying problems of organic electrochemistry .

This book presents various examples of how advanced fluorescence and spectroscopic analytical methods can be used in combination with computer data processing to address different biochemical questions. The main focus is on evolutionary biochemistry and the description of biochemical and metabolic issues; specifically, the use of pulse amplitude modulated fluorescence (PAM) for the functional analysis of the cellular state, as well as results obtained by means of the derivative spectroscopy method characterizing structural reorganization of a cell under the influence of external factors, are discussed. The topics presented here will be of interest to biologists, geneticists, biophysicists and biochemists, as well as experts in analytical chemistry, pharmaceutical chemistry and radio chemistry and radio activation studies with protonen and alpha-particles. It also offers a valuable resource for advanced undergraduate and graduate students in biological, physical and chemical disciplines whose work involves derivative spectrophotometry and PAM-fluorescence.

Physical Methods in Heterocyclic Chemistry, Volume III provides information pertinent to ionization constants and ultraviolet spectra. This book discusses the methods for the prediction of ionization constants. Comprised of seven chapters, this volume starts with an overview of the ionization constants of a number of heterocyclic compounds. This text then describes the procedures that are usually followed when molecular structure determinations based on electron diffraction measurements are carried out. Other chapters consider the concept of group frequencies, which rests upon the experimental fact that certain groups of atom give rise to vibrational transitions which are close or at the same frequency irrespective of the particular molecule in which the group occurs. The final chapter deals with the optical rotatory power, which is the only generally accessible physical property by which enantiomers can be distinguished in isolation. Heterocyclic chemists, biochemists, molecular biologists, and researchers will find this book extremely useful.

This book presents contributions from some of the leading experts in spectroscopic techniques including infrared, Raman, NMR, fluorescence and Circular Dichroism spectroscopy. Structural characterization of biomolecules, cells, tissues and whole organisms are amongst the topics that were covered by these experts at the 14th European Conference on Spectroscopy of Biological Molecules (ECSBM2011), held at the University of Coimbra, Portugal, from 29th August to 3rd September 2011, of which this book contains the papers. The book would be particularly valuable for those interested in vibrational spectroscopy and imaging of cells and tissues, applications of spectroscopy in biotechnology, single cell studies and microbial characterization. It highlights the potential of spectroscopy and imaging in medical diagnosis and screening, and discusses issues related to methodology, including data acquisition, analysis and processing, that would be valuable for scientists who are new to the field. The book would be an important reference source for scientists in academia and industry as well as early stage researchers such as graduate students and post-doctoral researchers.

A Laboratory Manual of Analytical Methods of Protein Chemistry, Volume 5 presents the laboratory techniques for protein and polypeptide study. This book discusses the staining procedure for histones, which has a high degree of selectivity for basic proteins and the unique ability to visualize qualitative differences in terms of color changes. Organized into four chapters, this volume begins with an overview of the formalin-mediated ammoniacal-silver staining procedure as a selective stain for basic proteins and its application per cell and per extract. This text then examines the optical rotatory dispersion (ORD), which has advanced into a powerful tool for describing the conformations and conformational changes of biopolymers. Other chapters consider the application of ultrasensitive calorimetry to thermodynamic problems. This book discusses as well the principle of the technique, its instrumentation, and experimental procedures. The final chapter deals with the hydrodynamic densities and preferential hydration values for protein precipitates in concentrated salt solutions. This book is a valuable resource for chemists and biochemists.
