 Abstract    e r -S e ite n b a n d v e r f a h r e n : I R -S p e k tr o s k o p ie m it M ik ro w e lle n g e n a u ig k e it Diese Arbeit ist Herrn Professor Helmut Dreizler am Institut für Physikalische Chemie der Univer­ sität Kiel aus Anlaß seines sechzigsten Geburtstags gewidmet. Herr Dreizler hat mir als einer der ersten die Idee vermittelt, die ursprünglich so unterschiedlichen Methoden der Mikrowellen und des Infraroten spektroskopisch als Einheit zu sehen. Dafür möchte ich ihm danken. W . A. Kreiner Infrared spectroscopy with laser sidebands at microwave modulation frequencies Infrared spectroscopy with laser sidebands at microwave modulation frequencies (12 18 GHz) is described. After the basics of this technique several examples of saturation spectroscopy on gaseous molecules are given. As a result it is shown that, in the infrared between 900 and 1100 cm" \ this broadband tunable laser source achieves resolution (3 parts in 109) as well as absolute accuracy in frequency measurement (± 3 x 10~6 cm-1) which are comparable to microwave spectroscopy.

 Title    The Diode Laser Spectrum of Bromine Monofluoride (BrF) in the Ground Electronic State  
 Abstract    The infrared absorption spectra of the two isotopic forms of bromine monofluoride in natural abundance (79 BrF: 50.54%, 81 BrF: 49.46%) in their ground electronic state (^T) have been measured, using a diode laser spectrometer. These data were fitted along with the published infrared and microwave spectra to produce an improved set of Dunham F-parameters and a set of mass-indepen-dent parameters. Also, the coefficients of the Dunham potential function of bromine monofluoride were determined by a direct fit to the experimental data.
