Preface

Infrared (IR) spectroscopy is a well-established spectroscopic technique that has seen major advances over the past two centuries. Being easy to operate, nondestructive, with a capability of elucidating and quantifying both organic and inorganic materials from different matrices and even in miniature quantities, and offering a *fingerprint* profile for each molecule, makes IR an inestimable analytical technique. The introduction of gratings, interferometers, supercomputers, and the availability of expeditious data analysis approaches together with the growth of IR spectroscopy have paralleled one another. These advances and how they have been greatly reflected in the applications of IR spectroscopy in different realms were

The material revealed in this book incorporates and blends the fundamentals of IR spectroscopy, the advances assimilated in the field of IR, and a variety of applications: detection of high explosives, biological threats, analysis of pharmaceuticals, monitoring of gas emission and air quality in an industrial environment, early-stage detection of serious health problems like obesity, assessing quality parameters of fruit, study of radiation-stimulated processes of adsorption, radiolysis of hydrocarbons on metal surfaces, radiation hydrogenation of these surfaces, and ideal catalyst

From the fundamentals to the applications and throughout the advances, it is our hope that this book will be considered as a reference on IR spectroscopy. The authors of each chapter have tried to appeal to readers from different backgrounds

Finally, I would like to thank all the authors who have contributed to this book by writing a chapter. They are all experts in their fields and have exerted time and effort to make this book a comprehensive, informative piece. Special thanks to the Department of Chemistry and Earth Sciences, Qatar University, Doha, for facilitating my task as editor of this book. I owe much to my son, Yusuf (Y6, QIS, Doha), for his help in creating the diagrams and presentations given in the introductory chapter. Last, but by no means least, I am grateful to my family for all the love,
