✦ Synopsis
The structure of cyclobutadiene has been a topic of considerable interest.
Theoretical calculations have predicted a singlet ground state with Dzh symmetry[Zl and experimental results have generally been consistent with this structure.
[3] Recently, however, strong evidence has been presented which indicates cyclobutadiene has Dqh symmetry. [4] We report here our results on tetramethyl cyclobutadiene (TMCB) which suggest that this compound has a singlet ground state.
