Spectroscopy provides a window into the atomic and molecular structure of substances by studying their interaction with electromagnetic radiation. It is a cornerstone of analytical chemistry and material identification. Introduction to Spectroscopy offers a detailed exploration of UV-Vis, IR, NMR, and mass spectroscopic techniques. The book explains theoretical foundations, instrumentation, and data interpretation methods. It also includes practical examples that link spectra to molecular structures. With a clear and systematic approach, this book equips readers with the analytical skills necessary for chemical analysis and research.
