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.

The goal of this course is to illustrate how molecular structure is extracted from a spectrum. In order to achieve this goal it will be necessary to:
This will, in large part, be a course in applied, stationary state quantum mechanics. Aside from the last few lectures, the focus will be on energy levels, structure, and spectra, rather than experimental techniques and apparatus.
Formal requirements include:
Bernath, P. F. Spectra of Atoms and Molecules. New York, NY: Oxford University Press, 1995. ISBN: 9780195075984.
Hougen, J. T. "NBS Monograph 115." A version of "NBS Monograph 115" is available online through the National Institute of Standards and Technology.
Wilson, E. B., J. C. Decius, and P. C. Cross. Molecular Vibrations. New York, NY: McGraw-Hill, 1955.
The approach and specific material covered in Bernath's "Spectra of Atoms and Molecules" will be quite different from the lectures.
