Syllabus (CHEMISTRY)

Course Type: MAJ-17

Semester: 8

Course Code: BCEMMAJ17C

Course Title: Physical Chemistry – VI

(L-P-Tu): 3-1-0

Credit: 4

Practical/Theory: Combined

Course Objective: Course Objectives of Major – 17 This major has four modules to cover. The following are the individual objectives of the respective modules. This major is, to some extent, an advanced-level course required for the next level of higher studies.

Learning Outcome: The Course Outcomes of Major-17: CO - 17.1: This particular module focuses mainly on the understanding and analysis of NMR/ PMR spectroscopy. The chapter discusses mainly topics like chemical shift and shielding, spin interactions, and equivalent protons

THEORY:

SPIN RESONANCE SPECTROSCOPY: (5 L)

Principles of NMR/ESR spectroscopy, Larmor precession, chemical shift and low resolution spectra, different scales, spin-spin coupling and high resolution spectra, interpretation of PMR spectra of organic molecules.

Group theory II: (20 lectures)

The Great Orthogonality Theorem: statement and interpretation, proof of important corollaries; construction of character tables: construction of their character tables for abelian and cyclic groups. Direct product groups and construction of their character tables, direct product representations, reduction formula, vanishing of integrals and its applications, invariance of the Hamiltonian operator and eigen functions of H as bases of irreducible representations.

Projection operators (without derivation), application of group theoretical methods for (i) construction of SALC’s and their use in calculation of π MO’s under the Huckel approximations, (ii) symmetry aspects of molecular vibrations: infrared and Raman activity.

Quantum mechanics (10L):

de Broglie wavelength, Bohr’s correspondence principle with examples; properties of wave functions, operators and related theorems.Schrödinger equation, energy-eigenvalue equation, expectation value, eigenvalue and spread of observation, definition of uncertainty; equation of motion, constants of motion; detailed treatment of the particle in a box, including degeneracy; step potential and tunneling.

Atomic spectra: (10 L):

Quantum numbers, orbital and spin angular momenta of electrons, Stern-Gerlach experiment, vector atom model, term symbols (one and two optical electron systems), normal and anomalous Zeeman effect, Paschen back effect.

Introduction to Molecular Term Symbols.
