Lec 2 | Small-Molecule Spectroscopy and Dynamics
This video lecture series on Small-Molecule Spectroscopy and Dynamics by Prof. Eric Grimson and Prof. John Guttag illustrates 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),and the notation of atomic and molecular spectroscopy........
