Spectroscopic techniques form the largest and most important single group of techniques used in Chemistry. This book takes a tutorial approach to the use of spectroscopic measurement techniques in analytical science, providing immediate guidance and advice to individuals in the course of their work. Each topic has been written in a clear and explanatory style to provide both straightforward concepts and invaluable background information. This approach, combined with an extensive cross referencing system, enables the reader to provide straightforward concepts in valuable background information and enables the reader to place each chapter into a broader scientific context. This book aims to provide students and practicing spectroscopists with an introduction and guide to the application of analytical techniques. It also aims to provide the reader with sufficient detail of fundamental techniques to encourage further study and exploration in the field of spectroscopy.
