Physical Chemistry: A Molcular Approach
Course Details:
Understanding chemistry is nothing but to understand science in terms of molecules & their interactions and we believe that a course in physical chemistry should reflect this viewpoint. The main focus of modern physical chemistry is on the molecules. In this course thermodynamics will be used to describe macroscopic chemical systems. Students will learn how thermodynamics can be formulated in terms of the properties of atoms & molecules that make up macroscopic chemical systems - using the tools of quantum mechanics. Statistical mechanics will be used to describe thermodynamics at a molecular level. Understanding of quantum mechanics, thermodynamics & statistical mechanics will be used to understand molecular spectroscopy, reaction dynamics & surface phenomena.
Module 1: Concepts of Classical Mechanics
Good Coordinates, Energy, Hamiltonian & Angular Momentum, the state of a system, classical wave equation - vibrating string, vibrating membrane.
Module 2: Concepts of Quantum Mechanics
Work of Planck, Einstein, Bohr, Born & Heisenberg, Waves vs. Particles, de Broglie hypothesis, postulates of Quantum Mechanics – operators, eigenfunctions, eigenvalues, function spaces, Superposition & compatible observables, Time development, Conservation Theorems & Parity, one dimensional problems, bound and unbound states.
Module 3: Quantum Chemistry
Hydrogen atom- exact solution, Helium atom – approximate solution, variational method, perturbation method, Multi-electron atom, chemical bond – diatomic molecule, bonding in polyatomic molecules, symmetry can be described by a set of symmetry elements, symmetry operations form a group & represented by matrices, character table, Irreducible representation.
Module 4: Introduction to Statistical Mechanics
Boltzmann factor & partition function, Molecular partition function: partition function of each degree of freedom, Partition functions: real gas vs real gas.
Module 5: Introduction to Thermodynamics
Molecular interpretation of Laws of Thermodynamics, adiabatic process, heat capacity, heat of reaction, spontaneous process, entropy and partition function, statistical thermodynamics, spectroscopic entropy vs. calorimetric entropy, Helmhotz & Gibbs Gibbs energies, phase equilibria, chemical equilibria.
Module 6: Introduction to Spectroscopy
