This textbook has been conceptualized for B.Sc. Fourth Semester students of Chemistry as per the latest curriculum on the directives of NEP 2020 - for the Universities of UP. Maintaining the traditional approach to the subject, this textbook comprehensively covers two papers, namely Theory and Practical Parts. Quantum Mechanics and Analytical Techniques for Theory Part and Instrumental Analysis for Practical Part. The topics covered in the book are Atomic Structure, Elementary Quantum Mechanics, Molecular Spectroscopy (Rotational, Vibrational, Roman and Electronic Spectra), UV-Visible Spectroscopy, Infrared Spectroscopy, 1H —NMR Spectroscopy (PMR), Introduction to Mass Spectrometry, Separation Techniques in the Theory Part. The Practical Part covering Molecular Weight Determination, Spectrophotometry, Spectroscopy, and Chromatographic Separations have been presented systematically to help students in achieving solid conceptional understanding and learn experimental procedures.
