This book provides a straightforward introduction to the spectroscopy of diatomic molecules and is written at the level of intermediate undergraduate courses in physical chemistry and chemical physics. Following a general introduction to the subject, the second chapter lays out the essential quantum mechanical tools required to understand spectroscopy. Very little previous knowledge is assumed; mathematics is kept to a minimum, the treatment being only semi-quantitative. The following chapter uses this quantum mechanical framework to establish the selection rules which govern spectroscopic transitions. Chapters 4 - 7 describe the various branches of spectroscopy covered by the book; rotational, rotational - vibrational, Raman, and electronic spectroscopy. Quantum mechanics is used to derive formulae for the various energy levels involved and for the relative intensities of different types of transition. From these, the appearances of the different types of spectra are derived. The molecular parameters on which these spectra depend are defined and the structural information which can be derived from these is discussed.

Written to be the definitive text on the rotational spectroscopy of diatomic molecules, this book develops the theory behind the energy levels of diatomic molecules and then summarises the many experimental methods used to study their spectra in the gaseous state. After a general introduction, the methods used to separate nuclear and electronic motions are described. Brown and Carrington then show how the fundamental Dirac and Breit equations may be developed to provide comprehensive descriptions of the kinetic and potential energy terms which govern the behaviour of the electrons. One chapter is devoted solely to angular momentum theory and another describes the development of the so-called effective Hamiltonians used to analyse and understand the experimental spectra of diatomic molecules. The remainder of the book concentrates on experimental methods. This book will be of interest to graduate students and researchers interested in the rotational spectroscopy of diatomic molecules.

This supplement to McCance and Widdowson's The Composition of Foods 5th Edition provides the only authoritative, up-to-date and extensive compilation of nutrient composition data for a wide range of miscellaneous foods available in the UK. Miscellaneous Foods provides data on up to 80 nutrients for 418 foods, over half of which have not been reported before. The coverage includes fats, oils, sugars, preserves, confectionery, savoury snacks, alcoholic beverages, soft drinks, soups, sauces, pickles and baby foods. The composition data are expressed in the main tables per 100g or 100ml of food for 45 nutrients, which include proximates, individual sugars, fibre, total fatty acids, cholesterol, inorganic constituents, vitamins, and alcohol for the alcoholic drinks. Supplementary tables provide data for vitamin E fractions, individual fatty acids and % alcohol by volume for selected beers and wines. The book also includes new recipes for a significant number of soups, sauces and confectionery items, and a comprehensive index.

Meat, Poultry and Game forms a major update to The Composition of Foods 5th Edition, providing new and extensive nutritional composition data for 429 foods in this significant food group. It provides new information on both raw and cooked meats, including lamb, pork, beef, veal, chicken, turkey, duck, grouse, goose, pheasant, pigeon, hare, rabbit, venison, heart, kidney, liver, oxtail, sweetbread and tongue. Easy-to-read tables provide composition data (per 100g of food) for up to 62 nutrients. The main tables list data for 42 nutrients, and supplementary tables include individual fatty acids (expressed per 100g of total fatty acids), retinol fractions, and vitamin D fractions for selected foods. There are also details on cooking methods, weight losses on cooking meats, a listing of taxonomic and alternative food names, and a food index. Meat, Poultry and Game forms an essential, authoritative and up-to-date source of new nutrient data. It is an essential reference source for professionals and students of food science and nutrition and will also be of interest to the layperson with interests in diet and nutrition.

This supplement to McCance and Widdowson's The Composition of Foods 5th Edition presents in-depth information on the nutrient content of fish, crustacea, molluscs, fish products and fish dishes available in the UK. All previously published data have been updated and revised, and Fish and Fish Products now provides composition values for 308 foods, over 200 of which have not been covered before. The new nutrient composition information includes extensive individual fatty acid data. The foods covered in Fish and Fish Products take account of increasingly popular varieties now eaten, such as fresh sardines, red mullet and monkfish; fish prepared by different cooking methods including grilling and steaming; fish eaten by ethnic communities; fish available from fish and chip shops; and the wide variety of fish products now available such as seafood cocktail and taramasalata. The data provided covers both raw and cooked fish, and the main tables cover 42 nutrients per food. Included are inorganics and trace elements, vitamins, total fatty acids and cholesterol. Supplementary tables cover individual fatty acids per 100 grams of food, individual sugars, vitamin E fractions, retinol fractions, taxonomic and alternative names. Fish and Fish Products is the authoritative reference source for nutritionists, dietitians and others interested in the nutritional composition of this food group. It is the only source of complete and up-to-date compositional data appropriate to the UK, much of which has never been published before. This supplement will also be of interest to those in other countries whose diet includes fish.

This supplement to McCance and Widdowson's The Composition of Foods 5th Edition, provides authoritative and evaluated new nutrient composition data for over 280 popular meat-based products and dishes. The coverage reflects the changes to meat-based food now consumed in the UK, and new nutritional information is given for bacon and ham, burgers and grillsteaks, meat pies and pastries, sausages and patÚs, as well as manufactured ready-meals, healthy-eating options and dishes prepared in the home. The easy-to-read main tables provide composition data (per 100g of food) for up to 40 nutrients, and supplementary tables provide information on vitamin D fractions and individual fatty acids. The appendices detail percentage weight loss on cooking and provide a comprehensive food index. In addition, the book contains recipes for approximately 100 dishes. Meat Products and Dishes updates and greatly extends all existing data for this food group from McCance and Widdowson's The Composition of Foods 5th Edition and is a unique source of new information. This book will have many applications: in planning individual diets and menus, calculating recipes, teaching and research, as well as being of appeal to the layperson with an interest in diet and nutrition.
