Fundamentals of Absorption Spectroscopy

Fundamentals of Absorption Spectroscopy offers a clear and comprehensive introduction to the principles, instrumentation, and applications of absorption spectroscopy across UV-Visible, IR, and other spectral regions. Designed for students, researchers, and industry professionals, this book bridges theory and practice with practical illustrations and real-world case studies, providing a solid foundation in both fundamental concepts and contemporary applications in chemistry, biology, medicine, environmental monitoring, and materials science. It fills the gap between overly advanced and overly simplified texts by combining fundamental theory with practical insights, particularly from biological perspectives. This book addresses the need for an updated, student-friendly, and application-oriented resource in absorption spectroscopy. Readers will benefit from structured guidance that connects theoretical principles with experimental data, explains instrumentation and its limitations, and demonstrates applications across diverse fields such as pharmaceuticals, environmental analysis, and biomolecular sciences. The inclusion of case studies and recent advances in spectroscopic technology ensures relevance for both academic study and professional practice.
