Molecular Symmetry in Cyclopentadienyl Thallium and Some Related Substances from their Microwave Spectra

Abstract

IT was recently found in this laboratory1 that the symmetry of cyclopentadienyl nickel nitrosyl is simply and unequivocally shown by its microwave spectrum. We have now applied the same method to demonstrate the symmetries of cyclopentadienyl thallium, cyclopentadienyl manganese tricarbonyl and benzene chromium tricarbonyl. The manganese compound had sufficient vapour pressure at room temperature, but the other materials were studied in a Stark modulation spectrometer operated at about 100° C.
