Abstract

The rotational spectra of the three symmetric top molecules of the title have been measured and the rotational constants determined. The latter are in agreement with those obtained from chemically reasonable molecular models. The spectrum of bullvalene shows an interesting vibrational structure.

Microwave and low-frequency vibrational spectra of bullvalene
1976, Journal of Molecular Spectroscopy
The microwave spectrum of bullvalene has been investigated in the region 18–40 GHz. In addition to transitions in the ground vibrational state, transitions arising from five excited vibrational states below 600 cm⁻¹ have also been observed. A combination of microwave intensity measurements and infrared and Raman data has been utilized to assign these vibrations. Three of the vibrations are E-type modes at 241, 355, and 588 cm⁻¹. One is an A₁-type mode at 445 cm⁻¹, and another is an A₂-type at 266 cm⁻¹. The microwave spectrum indicates the presence of a first-order Coriolis interaction for the E modes at 241 and 588 cm⁻¹. The first-order Coriolis coupling constant q = 0.557 MHz for the 241 cm⁻¹ vibration. The spectral results are consistent with C_3v symmetry for bullvalene.
