Book Description
Stereodynamics of Molecular Systems covers the proceedings of a symposium held at the State University of New York at Albany, on 23-24 April 1979. The book focuses on the stereodynamics of molecules and ions and nucleic acid structure. The contributions tackle spectroscopy, crystallography, perturbations, and electron-transfer reactions. The selection first offers information on nuclear magnetic resonance spectroscopy chemical shifts, coupling constants, and molecular geometry, including chemical shifts, bond coupling constants, and constitutional features of nucleic acids. The book then takes a look at nuclear magnetic resonance spectroscopy stereodynamics of small molecules; nuclear magnetic resonance spectroscopy solution dynamics of polymer chains; and single crystal crystallography. The publication evaluates the steric effects on electron-transfer reactions of sulfonamides; effects of isotopic perturbation on NMR spectra; and conformational mobility of the backbone of cyclic tripeptides. The book also discusses accessible surface areas of nucleic acids and their relation to folding, conformational transition, and protein recognition. Topics include polarity of exposed atoms, surface of DNA double helices, transfer RNA, and calculation of “static“ accessible surface area. The selection is a dependable reference for readers interested in the stereodynamics of molecules and ions and nucleic acid structure.

Book Description
In recent years, there has been rapid growth in the research field of real-time observation of nuclear and electronic dynamics in molecules. Its time range extends from femtoseconds to attoseconds. This has been made possible by the development of both laser technology and time-dependent theoretical treatments. Indeed, this research field is arguably the most active one in molecular science, second only to femtosecond chemistry. The outcome of the research is expected to make an important contribution to physics, materials science and biology as well as chemistry. In this monograph, the fundamental theories and methods, as well as experimental methods and results, of real-time observation of both nuclear and electronic motions in molecular systems are described. It is suitable for researchers who want to make an active contribution to the new research field and for graduate students who are interested in ultra-fast nuclear and electron dynamics in molecular systems.

Book Description
DNA sequence specificity is a sub-specialty in the general area of molecular recognition. This area includes macromolecular-molecular interactions (e.g., protein-DNA), oligomer-DNA interacitons (e.g., triple strands), and ligand-DNA interactions (e.g., drug-DNA). It is this latter group of DNA sequence specificity interactions that is the subject of Volumes 1 and 2 of Advances in DNA Sequence Specific Agents. As was the case for Volume 1, Part A also covers methodology, but in Volume 2 we include calorimetric titrations, molecular modeling, X-ray crystallographic and NMR structural studies, and transcriptional assays. Part B also follows the same format as Volume 1 and describes the sequence specificities and covalent and noncovalent interactions of small ligands with DNA.This volume is aimed in general at scientists who have an interest in deciphering the molecular mechanisms for sequence recognition of DNA. The methods have general applicability to small molecules as well as oligomers and proteins, while the examples provide general principles involved in sequence recognition.

Book Description
Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Book Description
Phosphorous-31 NMR: Principles and Applications focuses on the evolution of phosphorus-31 nuclear magnetic resonance (NMR) as a widely applied spectroscopic probe of the structure and dynamics of phosphorus-containing compounds. The selection first offers information on the principles and empirical observations of phosphorus-31 chemical shifts and the principles and applications of phosphorus-31 spin-spin coupling constants. Discussions focus on introduction and basic principles, directly bonded phosphorus coupling constants, and two-bond and three-bond coupling constants. The text then ponders on phosphorus-31 NMR of enzyme complexes and paramagnetic probes of enzyme complexes with phosphorus-containing compounds. The manuscript elaborates on the use of chiral thiophosphates and the stereochemistry of enzymatic phosphoryl transfer and DNA and RNA conformations. Topics include helix-coil transitions, sequence dependence of double-stranded DNA conformations, dynamic behavior of RNA and DNA, biological and genetic significance, and stereochemical problems studied with chiral thiophosphates. The conformation and dynamics of nucleic acids and phosphoproteins, relaxation behavior of nucleic acids, and theory and applications of solid-state phosphorus-31 NMR to nucleic acids are also discussed. The selection is a valuable reference for readers interested in the principles and applications of phosphorus-31 nuclear magnetic resonance.

Book Description
This unique work brings together contributions from the world's foremost authorities on a subject of wide-ranging importance both to continued scientific investigation and major industrial processes. Carbocations are involved in petroleum cracking and refining, coal processing, polymerization chemistry, synthetically important solvolytic reactions, isomerizations and rearrangements, addition reactions, aromatic substitutions, and a variety of biosynthetic transformations. Stable Carbocation Chemistry offers a broad and representative view of the entire field, including * Carbocation history and development * Generation of intriguing classes of carbocations and carbodications * Application and development of spectroscopic techniques * Use of long-lived stable ion conditions to carry out practical synthetic transformations * And more Dedicated to George Olah for his pioneering and inspirational efforts in the field, Stable Carbocation Chemistry uncovers fertile ground for continued research and further practical application in this dynamic and still-growing field.
