Molecular Spectroscopy: A Physical Chemist’s perspective

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 BombayINTENDED AUDIENCE : Chemistry, Physics and UG students of EngineeringPREREQUISITES :Nil.INDUSTRY SUPPORT : Nil.
