Introductory Quantum Chemistry

Instructor: Prof. K. L. Sebastian, Department of Inorganic and Physical Chemistry, IISc Bangalore.

The course will introduce quantum mechanics as applied to chemistry and would be structured such that B.Sc. students can follow, provided they have familiarity with differential equations. Topics covered in this course include Introduction to quantum mechanics, Postulates of quantum mechanics, particle in a box, Quantum tunneling, Harmonic oscillator, Hydrogen atom, Uncertainty principle, Angular momentum, and Chemical bonding.
