## Abstract The photoelectron spectrum of tetrakis (methylidene)cyclobutane (**1**, β[4]radialeneβ) is reported. The electronic states of **1**^+^ are assigned on the basis of model calculations and with reference to related systems. __Jahn__β__Teller__ activity in the degenerate states is discusse
