Courses taught by Prof. Anindya Datta, with active participation of students and postdoctoral fellows from the group as well as from other groups: CH-107: Physical Chemistry, CH-229: Chemical thermodynamics, CH-426: Rate processes in Chemistry, CH-442: Molecular Spectroscopy, and CH-801: Symmetry in Chemistry, CH-808: Ultrafast processes in chemistry.

This course provides a quantitative treatment of symmetry in chemistry, using group theory. We start with determination of point group, discuss transformation matrices, abstract group theory, unitary transformations, derivation of the Great Orthogonality Theorem and its consequences leading to character tables. Then, various applications in Chemistry are discussed. It is equivalent to CH 801 of IIT Bombay. The lectures are already recorded by CDEEP, IIT Bombay.
This is a comprehensive course on molecular spectroscopy. We start with dispersive and Fourier transform spectroscopic techniques, go on to derive selection rules from Time dependent perturbation theory, develop a quantum mechanical treatment of spin resonance spectroscopy and then move on to a discussion of spectra of polyatomic molecules using symmetry. This course is the same as CH 442 of IIT Bombay

This course is specifically designed for the BTech/BE engineering students. An appropriate contribution from all the core areas of chemistry (physical, inorganic, and organic) has been assembled here to provide the students an in-depth understanding of the fundamental topics. Additionally, the course outline has been designed to ensure the exposure of the students to chemistry-related interdisciplinary topics that will aid the students later in their core subject areas.
