The Porphyrins, Volume IV: Physical Chemistry, Part B focuses on the physical chemistry of porphyrins, their precursors, catabolic derivatives, and related compounds. The book covers nuclear magnetic resonance (NMR) spectroscopy of diamagnetic and paramagnetic porphyrins and electron nuclear double resonance (ENDOR) spectroscopy of chlorophylls and related systems. It also encompasses electron spin resonance (ESR) spectroscopy of porphyrin pi cations and anions, porphyrin excited states, metalloporphyrins, hemoproteins, and hemes. This volume is organized into nine chapters and begins with an overview of NMR theory and the use of NMR spectroscopy to study diamagnetic porphyrins and paramagnetic metalloporphyrins. The discussion then shifts to the theory of ENDOR spectroscopy and the application of ENDOR spectroscopy to analysis of chlorophylls, ESR of pi cations and anions of porphyrins as well as porphyrin excited states, and electron paramagnetic resonance and Mossbauer spectra of hemoproteins. The reader is also introduced to ESR and the electronic structure of metalloporphyrins. A chapter on Mossbauer spectroscopy of iron porphyrins concludes the book. This book is a valuable resource for inorganic, organic, physical, and biochemists interested in the physical chemistry of porphyrins.

Biological Electrochemistry, Volume I is a result of a series of lectures given regarding the electrochemistry of small and large organic and inorganic molecules and how electrochemical information helps in understanding some of the biological redox reactions of these systems. This volume ultimately focuses on the electrochemistry of small and macromolecular organic compounds. This book is divided into seven chapters where each focuses on a particular organic compound. These compounds are quinones, catecholamines, phenothiazines, ascorbic acid, purines, vitamin B12 and related compounds, and proteins. Each chapter starts with a brief introduction to the compounds and then its structure and electrochemistry aspect. The last chapter gives a detailed discussion on different kinds of proteins and their electrochemistry aspects. This volume will be of help to students as well as electrochemists, biochemists, biologists, and other scientists in the field of biotechnology.

Electrochemistry of Biological Molecules presents a fairly complete summary of the electrochemistry of the more important groups of nitrogen heterocyclic molecules including purines and pyrimidines and their nucleosides and nucleotides, polynucleotides and nucleic acids, pteridines, flavins, pyrroles, porphyrins, and pyridines. Topics covered range from the theory and instrumentation of electrochemistry to various biological molecules, including pteridines, isoalloxazines, flavins, and flavin nucleotides. Comprised of nine chapters, this book begins with an overview of electrochemical techniques and their use to study biological materials, followed by a discussion on the theory and instrumentation of electrochemistry, with emphasis on their significance and utility as well aa their principles and circuits. Subsequent chapters explore nitrogen heterocyclic molecules such as purines and pyrimidines and their nucleosides and nucleotides, polynucleotides and nucleic acids, pteridines, flavins, pyrroles, porphyrins, and pyridines. The electrochemistry of biologically important pyridines is considered. This monograph should be of value to electrochemists, biochemists, and biologists.

Rydberg Series in Atoms and Molecules deals with the Rydberg states of atomic and molecular systems. Rydberg series in atomic spectra and of diatomic molecules are examined, along with Rydberg terms of polyatomic molecules such as hydrocarbons with triple bonds, hydrocarbon molecules with double bonds, and benzene and benzene derivatives. Comprised of four chapters, this book begins with an overview of the spectrum of the hydrogen atom, along with some elementary and useful concepts and definitions. Some difficulties in the classification of excited states of simple molecules into Rydberg and non-Rydberg states are highlighted. The next chapter considers Rydberg series in atomic spectra and theoretical methods for quantitative description of atomic structures. One-electron models for Rydberg terms are also described, together with Rydberg series of diatomic molecules such as N2 and O2, CO and NO, and bromine and iodine. The final chapter is devoted to Rydberg terms of polyatomic molecules including hydrocarbons with triple and double bonds; benzene and benzene derivatives; hydrides with central atom; saturated hydrocarbons; and aldehydes and ketones.

This book describes alternative technologies for each of the major organic components of peat, including solvent extraction of peat bitumens; decolorization and oxidation of peat waxes; acid hydrolysis of unfractionated peat; and coke production. Other chapters discuss chemical characterization and analysis of peat; composition and hydrolysis of peat carbohydrates; composition of peat hydrolysates intended for yeast production; production of organic chemicals by peat hydrolysis; and scale of peat chemical operations. The final chapter examines the ecological and other environmental factors affecting the chemical technology of peat.

Biochemical Aspects of Plant-Parasite Relationships is a collection of papers from the Phytochemical Society Symposium of the same subject held at Hull in April 1975. This collection discusses biochemical research on the mechanisms involved in the invasion of plants by pathogens, the production of disease symptoms, and the mechanisms occurring in plant resistance against the invading microorganisms. Some papers discuss the genetics of fungal-plant interactions and the structural features of both infection and resistance processes, Such genetic interactions and structural features point to a biochemical reason for the plant-parasite interaction. Several attempts to correlate production of a cell wall degrading enzyme in vitro by a pathogen's virulence have shown great differences between in vitro and in vivo environments. One paper cites as an example the pathogens which produce both pectic hydrolases and lyases: the type of enzyme that is found to predominate often is actually associated with the pH of the environment. One paper also investigates nucleic acid transfer and the possible role of RNA in the host-parasite specificity. This collection can prove beneficial for microbiologists, biochemists, biotechnologists, plant biologists, and academicians connected with the biological sciences.
