Atomic and Molecular Spectroscopy

ABOUT THE EXPERIMENT
In this experiment you will examine the quantized energy levels in various atoms and molecules. A commercial fiber-optic-coupled spectrometer is used to examine emission spectra from plasma discharge sources. The results are analyzed quantitatively and allow you to verify the Bohr model for hydrogen, verify the famous spin-orbit splitting in Na, and also to understand the structure of the N2 molecule.
WHAT YOU WILL LEARN
  • Atomic physics: Bohr orbitals, measurement of the Rydberg constant, the spin-orbit coupling in sodium
  • Molecular physics: vibrational and rotational modes of diatomic molecules, band spectra, the chemical bond
  • Principles of grating spectroscopy with CCD readout
  • Use of the Ocean Optics fiber optics spectrometer system 
PREPARATION
  • H. Haken  and H. Wolf, The Physics of Atoms and Quanta, Chap. 8, 11, 12.
  • Diffraction Grating Handbook 4th Edition, by the Richardson Grating Laboratory, www.gratinglab.com, Chapter 2, and 6.2.
  • "Atomic and Molecular Spectroscopy" 441-442 Laboratory Procedure (PDF)
