Huckel Molecular Orbital Theory aims to be a simple, descriptive, and non-mathematical introduction to the Huckel molecular orbital theory and its applications in organic chemistry, thus the more basic text found in the book. The book, after an introduction to related concepts such as quantum mechanics and chemical bonding, discusses the Huckel molecular orbital theory and its basic assumptions; the variation principle and the basic Huckel method; and the use of symmetry properties in simplifying Huckel method orbital calculations. The book also covers other related topics such as the extensions and improvements of the simple Huckel method; the quantitative significance Huckel molecular orbital results; and the principle of conservation of orbital symmetry. The text is recommended for undergraduate students of organic chemistry who wish to be acquainted with the basics of the Huckel molecular orbital theory.
Polymers in Organic Electronics: Polymer Selection for Electronic, Mechatronic, and Optoelectronic Systems provides readers with vital data, guidelines, and techniques for optimally designing organic electronic systems using novel polymers. The book classifies polymer families, types, complexes, composites, nanocomposites, compounds, and small molecules while also providing an introduction to the fundamental principles of polymers and electronics. Features information on concepts and optimized types of electronics and a classification system of electronic polymers, including piezoelectric and pyroelectric, optoelectronic, mechatronic, organic electronic complexes, and more. The book is designed to help readers select the optimized material for structuring their organic electronic system.Chapters discuss the most common properties of electronic polymers, methods of optimization, and polymeric-structured printed circuit boards.

Applications of MO Theory in Organic Chemistry is a documentation of the proceedings of the First Theoretical Organic Chemistry meeting. This text is divided into five sections. Section A contains contributions ranging from the stereochemistry of stable molecules, radicals, and molecular ions, through hydrogen bonding and ion solvation to mathematical analyses of energy hypersurfaces. Section B deals with theoretical studies of organic reactions, including basecatalyzed hydrolysis, protonation, epoxidation, and electrophilic addition to double and triple bonds. Section C consists of topics starting with a qualitative configuration interaction treatment of thermal and photochemical organic reactions, followed by ab initio treatments of photochemical intermediates and a consideration of the role of Rydberg and valence-shell states in photochemistry. Section D provides analyses of methods for the determination and characterization of localized MO and discussions of correlated electron pair functions. Section E covers a very wide range from the application of statistical physics to the treatment of molecular interactions with their environments to a challenge to theoretical organic chemists in the field of natural products, and an introduction to information theory in organic chemistry. This book is a good source of information for students and researchers conducting study on the many areas in theoretical organic chemistry.
Includes entries for maps and atlases.
"Spectroscopy has become the organic chemist's most important tool in identifying compounds and studying their interactions. The arsenal of techniques available to the research chemist has, over the years, expanded from the familiar infrared, proton nmr and mass spectroscopy, to include the routine use of carbon-13 nmr spectroscopy and such modern methods of data acquisition as Fourier transform nmr, laser Raman spectroscopy, and UV spectroscopy. This book serves as an introduction to all of the major spectroscopic techniques, using over 200 actual spectra as examples, and providing a substantial number of problems and completely worked-through solutions that demonstrate how spectral techniques are applied to analytical problems. The book represents a significant departure from the scope of general spectroscopy texts. In addition to the usual chapters on infrared, proton nmr and mass spectroscopy, a number of increasingly important techniques have been included for the first time. Chapter 4, for instance, introduces not only the analysis of proton nmr spectra, but also describes iteration of theoretical nmr spectra for a best fit with observed experimental spectra using the popular LAOCOON III program. A complete FORTRAN listing for a conversational pendix I. Chapter 5 presents a non-mathematical description of Fourier transform nmr, including signal averaging, decoupling methods, quadrature detection, and the Fourier transform itself, and Chapter 6 goes on to describe Fourier transform techniques in carbon-13 spectroscopy. Chapter 7 introduces simple Huckel M.O. theory and the SHMO program for calculating the resonance stabilization of various systems, material which lays the groundwork for Chapter 8's discussion of ultraviolet spectroscopy using examples of ways in which energies can be correlated with SHMO parameters. A SHMO timesharing conversational program is listed in Appendix II. Finally, Chapter 10 outlines the organic chemical applications of laser Raman spectroscopy and the functional groups most easily identified using this method. Both organic chemists and graduate and advanced undergraduate students will find in the book's breadth of coverage an ideal introduction to the identification of organic compounds by spectroscopic means."- Publisher.

Spee's ships survived for as long as they did is a reflection of the primitive state of communications and methods of detection available in 1914. Their demise was as much by chance and coincidence at it was by good planning and concerted action by the British. The book includes material on several German and British ship and squadron commanders and provides a detailed overview of the opening months of the war in the Indian, Atlantic, and Pacific Oceans. The fact that.
