## Abstract The photoelectron spectra of quadricyclane (**3**) and 3βmethylidene quadricyclane (**4**) have been measured. The results served as a basis for the elucidation of the electronic structure of these compounds, which agreed with theoretical calculations. It is found that the symmetry of t
