Knowledge of thc chemical behavior of trace compounds in the atmosphere has grown steadily, and sometimes even spectacularly, in recent decades. These developments have led to the emergence of atmospheric chemistry as a new branch of science. This book covers all aspects of atmospheric chemistry on a global scale, integrating information from chemistry and geochemistry, physics, and biology to provide a unified account. For each atmospheric constituent of interest, the text summarizes the principal observations on global distribution, chemical reactions, natural and anthropogenic sources, and physical removal processes. Coverage includes processes in the gas phase, in aerosols and c1ouds, and in precipitation, as well as biogeochemical cycles and the evolution of the atmosphere. Chemistry of the Natural Atmosphere, Second Edition, will serve as a textbook for senior undergraduate and graduate courses, and as an essential reference for atmospheric chemists, meteorologists, and anyone studying the biogeochemical cycles of trace gases. * Updated extensively from the highly respected first edition * Treats the global-scale chemistry and distribution of atmospheric trace constituents * Emphasizes observations and their interpretation * Provides background on transport and reaction kinetics for interpretation of observational data * Includes chemistry in the gas phase and in aerosols and clouds * Details chemical reaction pathways for the most important trace constituents * Describes pertinent biogeochemical cycles * Written by an author with more than 40 years of research experience in atmospheric chemistry

This book explores chemical bonds, their intrinsic energies, and the corresponding dissociation energies which are relevant in reactivity problems. It offers the first book on conceptual quantum chemistry, a key area for understanding chemical principles and predicting chemical properties. It presents NBO mathematical algorithms embedded in a well-tested and widely used computer program (currently, NBO 5.9). While encouraging a "look under the hood" (Appendix A), this book mainly enables students to gain proficiency in using the NBO program to re-express complex wavefunctions in terms of intuitive chemical concepts and orbital imagery.

Chemistry of Marine Natural Products explores the marine environment and its chemical composition. This book discusses the factors that contribute to the increasing interest in the study of marine environment. Organized into five chapters, this text starts with a discussion on the organic compound isoprenoids. This book then examines the sterol composition in several species, including crustaceans, echinoderms, mollusks, and invertebrates. This text also discusses phenols and its derivatives, including bromophenols and dibrophenol. Amino acids, carbohydrates, and polymers are also presented in this book. Other chapters explain the secondary metabolites, particularly amino acids and simple amines. This book further discusses the chemistry of fatty acids and determines whether marine animals and plants elaborate any distinct fatty acids. The final chapter explores the biogenetic relationship of hydrocarbons to fatty acids. This book is intended for chemists with an interest in the marine environment. Oceanographers, marine biologists, marine scientists, pharmacologists, researchers, teachers, and students will find this book extremely useful.

Natural products play an integral and ongoing role in promoting numerous aspects of scientific advancement, and many aspects of basic research programs are intimately related to natural products. The significance, therefore, of the 28th volume in the Studies in Natural Product Chemistry series, edited by Professor Atta-ur-Rahman, cannot be overestimated. This volume, in accordance with previous volumes, presents us with cutting-edge contributions of great importance. The first paper presents over 100 compounds obtained from Broussonetia spp., and discusses biological activities. This is followed by similar contributions dealing with the genus Licania and Ginkgo biloba. Additional papers describe in detail a number of interesting and important natural compounds or structural classes: retinoids, tetramic acid metabolites, isoprenylated flavonoids, plant polyphenols, crocin, marcfortine and paraherquamide, acaricides, podolactones, triterpene glycosides and sulfur-containing marine compounds. An additional paper focuses on the antitumor activities of lipids, and a final contribution deals with natural product amelioration of cancer chemotherapy-induced adverse reactions.

Lignans, by convention, are a group of natural products that are formed by linking two phenylpropanoid units (C C units) by oxidative coupling. Most importantly, in 6 3 a lignan, two (C C units) are bound through the central carbon of their side chains, 6 3 0 i. e. the 8 and 8 positions (1, 2). The occurrence of C C -dimers, linked at sites other 6 3 0 than the 88 positions, is also known and these compounds have been termed neolignans (3, 4). As these two groups of compounds have close structural as well as biosynthetic relationships, they are often associated together and incorporated under the general term lignan (5). The diverse structural categorization of true lignans and of a few neolignans is presented in Fig. 1. Through the years, several review articles or books covering different facets of lignans, including their ch- istry (6, 7), biogenesis (8), synthesis (9), and biological activities (10) have been published. Enduring research for the investigation of secondary metabolites of plants has evidenced some compounds that are biogenetically related to true lignans or neolignans but bear some features not discerned in conventional lignans. These compounds or groups of compounds have been termed as non-conventional lignans, and include coumarinolignans, ?avonolignans, and stilbenolignans. The non-conventional lignans, like the conventional ones, have two C C units linked 6 3 together but have additional structural features to place them also under the category of coumarins, ?avonoids, or stilbenes.

Research in science education has recognized the importance of history and philosophy of science (HPS). Nature of science (NOS) is considered to be an essential part of HPS with important implications for teaching science. The role played by textbooks in developing students' informed conceptions of NOS has been a source of considerable interest for science educators. In some parts of the world, textbooks become the curriculum and determine to a great extent what is taught and learned in the classroom. Given this background and interest, this monograph has evaluated NOS in university level general chemistry textbooks published in U.S.A. Most textbooks in this study provided little insight with respect to the nine criteria used for evaluating NOS. Some of the textbooks, however, inevitably refer to HPS and thus provide guidelines for future textbooks. A few of the textbooks go into considerable detail to present the atomic models of Dalton, Thomson, Rutherford, Bohr and wave mechanical to illustrate the tentative nature of scientific theories --- an important NOS aspect. These results lead to the question: Are we teaching science as practiced by scientists? An answer to this question can help us to understand the importance of NOS, by providing students an HPS-based environment, so that they too (just like the scientists) feel the thrill and excitement of discovering new things. This monograph provides students and teachers guidelines for introducing various aspects of NOS, based on historical episodes.
