## Course being taught from 2006

#### JC210: Group Theory and Molecular Spectroscopy (August 3:0)

This course is an introduction to molecular spectroscopy applied to chemistry and biology. We hope to take up papers from literature and discuss along with developing the basis in the area of molecular spectroscopy. The course evaluation will be based on assignments, midterm and final examinations.

#### Syllabus:

Group Theory: Symmetry elements and operations, Products of operations, point groups, matrices and representations, reducible and irreducible character tables, Great orthogonality theorem, direct product of irreducible representation.

Magnetic Resonance: NMR and ESR spectroscopy, Experimental methods and applications, structure determinations, 2D NMR, MASNMR and MRI.

Vibrations and rotations of diatomic molecules: Nuclear motion in diatomics, anharmonicity, vibration-rotation coupling, potential energy functions, selection rules, rotational spectra, rotational-vibrational spectra. Vibrations of polyatomic molecules. Classical mechanics of vibrations, symmetry and normal vibrations, IR and Raman spectroscopy techniques including overtone excitation, stimulated emission pumping and resonance Ramana.

Electronic spectroscopy: Diatomic molecules, coupling of electronic and rotational angular momentum, analysis of vibronic and rot-vibronic spectra, electronic spectra of polyatomic molecules, Molecular orbitals and electronic states, electronic and vibronic selection rules, multi-photon spectroscopy, Experimental methods, ionic process and Koopman’s theorem, UV spectroscopy.

## Taught the following course in 2004 and 2005 along with Dr. Umesh V. Waghmare

#### JT 201: Solid State Physics (August 3:0)

This course is an introductory course in solid state physics for both masters as well as post masters students. The course aims at giving an over view on the topics in solid state physics. The course will have teaching hours as well as self study. The assessment of this course is based on the assignments from time to time and a final examinations conducted at the end of the course.

#### Syllabus:

Free Electron model, Crystal Structures and Symmetry, X-Ray Diffraction, Electrons in periodic lattices, Nearly Free Electron Approximation, Tight Binding Approximation, Fermi Surfaces, Phonons
