Electron momentum spectroscopy is applied to determine the character of the two outermost π orbitals of norbornadiene and 1,4-cyclohexadiene. From comparisons of observed and calculated electron momentum distributions, the highest occupied molecular orbital is experimentally identified as π- in the former and as π+ in the latter.
