Rotationally Resolved Electronic Stark Spectroscopy of 2,3-Benzofurane — •Marie-Luise Hebestreit, Michael Schneider, Hilda Lartian, and Michael Schmitt — Institute for Physical Chemistry I, Heinrich-Heine-University, Düsseldorf

The electronic origin of 2,3-benzofurane has been investigated using high resolution laser induced fluorescence spectroscopy (HRLIF) to analyze its electronic nature. The obtained molecular parameters from evolutionary algorithms were compared to the results of ab initio calculations. To investigate the permanent dipole moments in the ground and first excited state a homogeneous field was applied, which lifts the M degeneracy due to the Stark effect. Finally, the orientation of the transition dipole moment for the monomer is discussed and compared to that of indole in particular.
