This book describes the theory and practice of infrared and Raman spectroscopy as applied to the study of the physical and chemical characteristics of polymers. Its purpose is to give the beginning researcher in the field a firm foundation and a starting point for the study of more-advanced literature. To this end the book concentrates on the fundamentals of the theory and nomenclature, and on the discussion of well-documented illustrations of these fundamental principles, including many now-classic studies in the subject. No previous knowledge of either polymers or vibrational spectroscopy is assumed. The book will be of value to anyone beginning research on the vibrational spectroscopy of polymers, either from a physics or a chemistry background. It is intended to be especially suitable for use in undergraduate courses in physics, chemistry or materials science at both universities and polytechnics.
