A non-mathematical introduction to molecular spectroscopy. This revision includes: a chapter on the spectroscopy of surfaces and solids, new diagrams and problems, spectra that has been re-recorded on modern instruments, and enhanced applications of Fourier transform principles.

The Book Has 15 Chapters In All. The First Two Chapters Are Related To Atomic Structure And Atomic Spectra. The Next Chapter Is Devoted To Nature Of Chemical Bonds As Looked Upon Through Quantum Mechanics, Followed By All Types Of Spectroscopy. Every Aspect Is Explained With Some Typical Spectra. The Underlying Theory So Developed Will Help Students To Carry Out Spectral Analysis.Only Simple Quantum Mechanics Relevant To Simple Molecular Structure Has Been Given. Attempt Has Been Made To Relate The Characteristic Chemical Behavior Of These Molecules With Its Mo And Thus To Molecular Spectra. One Will Not Find Such Relationship In Any Book, But This Will Make Chemistry, As Such, Still More Interesting.Application Of Infrared And Ultra-Violet Spectroscopy, Nmr And Mass Spectra In Structure Determination Of Organic Molecules Are Very Elegantly Presented. In The Fourteenth Chapter, Lasers And Their Applications To Various Types Of Second, Third, And Fourth Order Scattering Spectroscopy Have Been Developed. The Book Has Minimum But Essential Mathematics With Very Easy Format In Its Text. Such An Approach Will Give A Clear Understanding Of The Subject And Provides Knowledge To Excel At Any Level University Examination, Competitive Examination, And Before Interview Boards.

A concise textbook bridging quantum theory and spectroscopy! Designed as a practical text, Quantum Mechanical Foundations of Molecular Spectroscopy covers the quantum mechanical fundamentals of molecular spectroscopy from the view of a professional spectroscopist, rather than a theoretician. Written by a noted expert on the topic, the book puts the emphasis on the relationship between spectroscopy and quantum mechanics, and provides the background information and derivations of the subjects needed to understand spectroscopy including: stationary energy states, transitions between these states, selection rules, and symmetry. The phenomenal growth of all forms of spectroscopy over the past eight decades has contributed enormously to our understanding of molecular structure and properties. Today spectroscopy covers a broad field including the modern magnetic resonance techniques, non-linear, laser and fiber-based spectroscopy, surface and surface-enhanced spectroscopy, pico- and femtosecond time resolved spectroscopy, and many more. This up-to-date resource discusses several forms of spectroscopy that are used in many fields of science, such as fluorescence, surface spectroscopies, linear and non-linear Raman spectroscopy and spin spectroscopy. This important text: Contains the physics and mathematics needed to understand spectroscopy Explores spectroscopic methods the are widely used in chemistry, biophysics, biology, and materials science Offers a text written by an experienced lecturer and practitioner of spectroscopic methods Includes detailed explanations and worked examples Written for chemistry, biochemistry, material sciences, and physics students, Quantum Mechanical Foundations of Molecular Spectroscopy provides an accessible text for understanding molecular spectroscopy.

A concise introduction to the spectroscopy of atoms and molecules. Treatment emphasizes an intuitive understanding of topics and the development of problem-solving techniques. Provides background material on time-dependent perturbation theory and second quantization, and incorporates many illustrative spectra from the literature. Examines electronic band spectra and polyatomic rotations, which makes accessible the energy levels and selection rules that govern microwave spectroscopy without recourse to detailed rotational eigenstates. Also covers triatomic molecules, aromatic hydrocarbons, lasers, multiphoton spectroscopies, and diagrammatic perturbation techniques.

Spectroscopy is the study of electromagnetic radiation and its interaction with solid, liquid, gas and plasma. It is one of the widely used analytical techniques to study the structure of atoms and molecules. The technique is also employed to obtain information about atoms and molecules as a result of their distinctive spectra. The fast-spreading field of spectroscopic applications has made a noteworthy influence on many disciplines, including energy research, chemical processing, environmental protection and medicine. This book aims to introduce students to the topic of spectroscopy. The author has avoided the mathematical aspects of the subject as far as possible; they appear in the text only when inevitable. Including topics such as time-dependent perturbation theory, laser action and applications of Group Theory in interpretation of spectra, the book offers a detailed coverage of the basic concepts and applications of spectroscopy.
