MIT OCW - 5.80 Small-Molecule Spectroscopy and Dynamics

MIT OCW - 5.80 Small-Molecule Spectroscopy and Dynamics (Fall 2008). This consists of 38 video lectures given by Prof. Robert Field. The goal of this course is to illustrate the spectroscopy of small molecules in the gas phase: quantum mechanical effective Hamiltonian models for rotational, vibrational, and electronic structure; transition selection rules and relative intensities; diagnostic patterns and experimental methods for the assignment of non-textbook spectra; breakdown of the Born-Oppenheimer approximation (spectroscopic perturbations); the stationary phase approximation; nondegenerate and quasidegenerate perturbation theory (van Vleck transformation); qualitative molecular orbital theory (Walsh diagrams); the notation of atomic and molecular spectroscopy.
