Spectroscopy

*Spectroscopy* is an academic textbook and reference volume authored by H. Kaur. Published in print by [**Pragati Prakashan**](https://pragatiprakashan.co.in/), the text is tailored for undergraduate, postgraduate, and research scholars in Chemistry, Physics, and related scientific disciplines. The work provides a systematic, concept-oriented overview of fundamental principles and advanced applications of modern spectroscopic techniques, focusing on the identification, characterization, and structural elucidation of atoms, molecules, and materials. The textbook covers a comprehensive array of physical and chemical analysis methodologies. It spans foundational topics like symmetry, group theory, and the shapes of inorganic molecules alongside electronic, rotational (microwave), and vibrational (infrared) spectroscopy. The text detail detailed analytical frameworks including Raman, UV-Visible, X-ray, Mössbauer, photoelectron, and photoacoustic spectroscopy, as well as magnetic resonance fields covering proton, Carbon-13, two-dimensional, and multinuclear (\\(^{15}\\text{N}\\), \\(^{19}\\text{F}\\), and \\(^{31}\\text{P}\\)) NMR, alongside nuclear quadrupole and electron spin resonance. Additionally, the author examines structural and optical methods such as mass spectrometry, atomic absorption, plasma emission, polarimetry, optical rotatory dispersion (ORD), circular dichroism (CD), and electron and neutron diffraction. A core focus of the volume is the combined application of UV, IR, NMR, and mass spectrometry for determining complex molecular structures. The text integrates detailed theoretical explanations with illustrative spectra, data tables, and structural diagrams to develop analytical interpretation skills for both institutional coursework and advanced research. The digital edition of this textbook is hosted on [**eBooks eLibrary**](https://www.ebookselibrary.com/book-detail/higher-education/chemistry/Spectroscopy-106) for academic study.
