It contains essential information and worked examples for those using vacuum technology in chemical applications and who are involved in the design and operation of vacuum equipment. Using step by step solutions of example calculations and formulae, Vacuum Technology: Calculations in Chemistry sets out to encourage readers to quantify their own systems so that they can ensure efficient operation and fault finding. Whilst emphasising the use of appropriate units in calculations and using well known expressions in vacuum technology throughout, the book includes: * formulae necessary for quantitative vacuum technology * commonly required data for common gases in tabulated form * schematic diagrams of systems and layouts This book is certain to be a confidence inspiring publication for use in both research and industry.
Basic Principles of Calculations in Chemistry is written specifically to assist students in understanding chemical calculations in the simplest way possible. Chemical and mathematical concepts are well simplified; the use of simple language and stepwise explanatory approach to solving quantitative problems are widely used in the book. Senior secondary school, high school and general pre-college students will find the book very useful as a study companion to the courses in their curriculum. College freshmen who want to understand chemical calculations from the basics will also find many of the chapters in this book helpful toward their courses. Hundreds of solved examples as well as challenging end-of-chapter exercises are some of the great features of this book. . Students studying for SAT I & II, GCSE, IGCSE, UTME, SSCE, HSC, and other similar examinations will benefit tremendously by studying all the chapters in this book conscientiously.
Ab Initio Valence Calculations in Chemistry describes the theory and practice of ab initio valence calculations in chemistry and applies the ideas to a specific example, linear BeH2. Topics covered include the Schrödinger equation and the orbital approximation to atomic orbitals; molecular orbital and valence bond methods; practical molecular wave functions; and molecular integrals. Open shell systems, molecular symmetry, and localized descriptions of electronic structure are also discussed. This book is comprised of 13 chapters and begins by introducing the reader to the use of the Schrödinger equation to solve the electronic structure of molecular systems. This discussion is followed by two chapters that describe the chemical and mathematical nature of orbital theories in quantum chemistry. Two general ways of using chemical and physical information in looking for approximate solutions of the Schrödinger equation are highlighted: model approximations and numerical approximations. Attention then turns to atomic orbitals as the basis of a description of molecular electronic structure; practical molecular wave functions; and a general strategy for performing molecular valence calculations. The final chapter examines the nature of the valence electronic structure by using invariance with respect to transformations among the occupied molecular orbitals and among the atomic orbitals. This text will be of interest to students and practitioners of chemistry, biochemistry, and quantum mechanics.

Ever thought there could be an easy way to master calculations in chemistry? Well, this book takes a practical and common sense approach to calculations in chemistry. Learners from GCSE/O'Levels right through to A Levels will find this book very indispensable as it covers calculations from the basics, starting from the building blocks of matter down to more complicated calculations in chemistry. This book touches on nearly all types of calculation you could come across in secondary school right up to second year in the university or college, gradually building up on the learners basic understandings of the inner workings of the subject.
Meant specifically for students studying chemistry at undergraduate and postgraduate levels, this book presents the calculations in chemistry in a simple, logical and down-to-earth manner that will impart students with the required numerical skills for excelling in chemistry.
Concepts & Calculations in Analytical Chemistry: A Spreadsheet Approach offers a novel approach to learning the fundamentals of chemical equilibria using the flexibility and power of a spreadsheet program. Through a conceptual presentation of chemical principles, this text will allow the reader to produce and digest large assemblies of numerical data/calculations while still focusing on the chemistry. The chapters are arranged in a logical sequence, identifying almost every equilibrium scenario that an analytical chemist is likely to encounter. The spreadsheet calculations and graphics offer an excellent solution to otherwise time-consuming operations. Worked examples are included throughout the book, and student-tested problems are featured at the end of each chapter. Spreadsheet commands for QuattroPro, Quattro, and Lotus 1-2-3 are embedded in the text. Concepts & Calculations in Analytical Chemistry: A Spreadsheet Approach has been designed to serve both as a supplement to an undergraduate quantitative analysis course or as a text in a graduate-level advanced analytical chemistry course. Professional chemists will also find this to be an excellent introduction to spreadsheet applications in the lab and a modern overview of analytical chemistry in a self-study format.
