چکیده

Laser excited, dispersed fluorescence spectra have been recorded for a number of bands of the ÖX~ electronic transition of CCl2 . Analysis of the data yields well defined values for the harmonic and anharmonic constants for the symmetric ground state vibrations. Additional lines are observed at red shifts 5000 cm 1 from the origin, which are not assignable in terms of the known X~ and à state structure. A possible explanation for these transitions would be perturbations of the singlet X~ structure by the low-lying triplet ã state.

The visible spectrum of zirconium dioxide, ZrO2.

The electronic spectrum of a cold molecular beam of zirconium dioxide, ZrO(2), has been investigated using laser induced fluorescence (LIF) in the region from 17,000 cm(-1) to 18,800 cm(-1) and by mass-resolved resonance enhanced multi-photon ionization (REMPI) spectroscopy from 17,000 cm(-1)-21,000 cm(-1). The LIF and REMPI spectra are assigned to progressions in the Ã(1)B(2)(ν(1), ν(2), ν(3))...
