The book Elementary Organic Spectroscopy offers a comprehensive and systematic introduction to the fundamental principles and practical applications of modern spectroscopic techniques used in organic chemistry. Designed for undergraduate and postgraduate students, this textbook combines theoretical depth with practical insight, covering a wide range of topics essential for the structural elucidation of organic compounds. The book begins with the basics of electromagnetic radiation and gradually explores various spectroscopic methods, including UV-Visible, Infra-red (IR), Raman, Nuclear Magnetic Resonance (NMR), Electron Spin Resonance (ESR) and Mass Spectrometry. Each chapter is rich in conceptual explanations, illustrative examples, spectral interpretations and real-world applications.
