Recent Advances in the Spectroscopy of Small Molecules

  • W. Demtröder
Conference paper


Three main reasons may be considered for the exciting progress achieved during recent years in molecular spectroscopy:
  1. 1.

    The use of lasers as spectroscopic light sources with all their advantages in high resolution spectroscopy.

  2. 2.

    The extension of modern spectroscopic techniques so far only used in atomic spectroscopy to the investigation of molecules (e.g. level crossing, double resonance, optical pumping, spin alignment).

  3. 3.

    The increase of theoretical interest in molecular physics and more rigorous computational studies of small molecules (e.g. computation of more accurate molecular wave functions, calculations of diatomic potential curves and dissociation energies and of triatomic potential surfaces).
