Physical Methods in Chemical Analysis, Volume III focuses on the application of physical methods in chemical analysis, including chromatography, spectroscopy, nuclear magnetic resonance, and photometry. The selection first offers information on gas chromatography, electrochromatography, and electroanalytical methods in trace analysis. Discussions focus on analytical applications, apparatus and techniques, titration methods, anodic stripping of deposited metals, and polarography. The book then examines the high-frequency method of chemical analysis, field emission microscopy, and theory and principles of sampling for chemical analysis. The publication takes a look at flame photometry and microwave spectroscopy. Topics include sample treatment required for flame photometric determinations; factors affecting precision and accuracy in flame photometry; theoretical background of microwave spectroscopy, and problems connected with quantitative analysis. The manuscript then elaborates on analytical applications of nuclear magnetic resonance; fluorescent x-ray spectrometric analysis; and neutron spectroscopy and neutron interactions in chemical analysis. The selection is a dependable reference for readers interested in the application of physical methods in chemical analysis.

A Molecular Conception of Organisms and Neoplasms

A Molecular Conception of Organisms and Neoplasms is a six-chapter thesis that consists of a chain of reasoning on the theory of molecular conception. This thesis contends that any organism, even if multicellular, is basically a single molecule, which is the key problem of the causation of neoplasms. After providing a unifying definition of a molecule, this book goes on discussing the concept of fundamental unicellularity of multicellular organism through protoplasmic continuity between its cells. The succeeding chapters highlight the principles of the molecular conception of organisms and neoplasms. The final chapters outline the other activities of an organism determined by the molecular conception theory, such as embryonic development, animal heat, movement, pleasure and pain, and mind. This book will be of value to biochemists and clinical chemists.

The Alkaloids

The Alkaloids: Chemistry and Physiology, Volume V: Pharmacology deals with the chemistry and pharmacology of the alkaloids. This book discusses the general pharmacology of morphine, cryptopine-like compounds, toad poisons, and respiratory stimulants. The appraisal of the utility of alkaloids as antimalarials, uterine stimulants, metabolism of cocaine, and optical isomerism-activity relationship are also elaborated. This publication likewise covers the parasympathetic blocking agents as mydriatics, methods of measuring mydriatic activity, alkaloids exhibiting curariform activity, and minor alkaloids of unknown structure. Other topics include the fate of morphine, tropane group, factors affecting cocaine anesthesia, and sympathomimetic mydriatics. This volume is intended for chemists and pharmacologists concerned with alkaloids.

Blood Group Substances

Blood Group Substances: Their Chemistry and Immunochemistry focuses on the characteristics, reactions, sources, and transformations of blood group substances. The book first offers information on human blood group factors and the methods and reagents used in testing for blood group antibodies and antigens. Topics include autoantibody formation and hemolytic anemia, panagglutinable erythrocytes, effects of temperature on hemagglutination, and effects of periodate on blood group substances. The text also ponders on the sources and purification of blood group substances. The publication examines the chemical and immunochemical characterization of blood group substances and immunochemical similarities and differences among blood group substances from various species. The text then takes a look at antibodies to blood group substances and their biological effects, including purification and concentration of blood group antibodies; studies with antibodies labeled with radioactive isotopes; and passage of antibodies through the placenta. The manuscript is a valuable reference for readers interested in blood group substances.

Determination of Organic Structures by Physical Methods

Determination of Organic Structures by Physical Methods, Volume 1 focuses on the processes, methodologies, principles, and approaches involved in the determination of organic structures by physical methods, including infrared light absorption, thermodynamic properties, Raman spectra, and kinetics. The selection first elaborates on the phase properties of small molecules, equilibrium and dynamic properties of large molecules, and optical rotation. Discussions focus on simple acyclic compounds, carbohydrates, steroids, diffusion, viscosity, osmotic pressure, sedimentation velocity, melting and boiling points, and molar volume. The book then examines ultraviolet and visible light absorption, infrared light absorption, Raman spectra, and the theory of magnetic susceptibility. Concerns cover applications to the study of organic compounds, applications to the determination of structure, determination of thermodynamic properties, and experimental methods and evaluation of data. The text ponders on wave-mechanical theory, reaction kinetics, and dissociation constants, including dissociation of molecular addition compounds, principles of reaction kinetics, and valence-bond treatment of aromatic systems. The selection is a valuable source of data for researchers interested in the determination of organic structures by physical methods.

Handbook of Hydrocarbons

Handbook of Hydrocarbons presents tables giving the most important physical properties of all hydrocarbons whose boiling points have been recorded, in such form that all compounds boiling at or near a given value are listed together and a specific hydrocarbon can be promptly located. These ends can be best accomplished by listing each hydrocarbon in each of two tables. The order in Table A is that of the boiling points at 760 mm Hg, and other properties are also given. In Table B, the compounds are in groups of the same empirical formula and same type and are arranged within groups alphabetically by parent compound. Table C lists alternate names, including common and trivial names, and Table D gives the numbering of representative cyclic hydrocarbons. The Handbook should offer real help to any investigator who wishes either to locate the properties of a specific hydrocarbon, or to obtain a quick summary of the indications which the literature affords as to what compounds may be present in a cut of known boiling point or range. Such investigators should include academic, institutional, government and industrial workers, not only in the predominantly hydrocarbon fields such as petroleum, natural gas, shale oil, coal, and rubber, but also in the chemical, ""petrochemical,"" and plastics fields.
