Electron transmission measurements yield vertical electron affinities of −1.93 eV for ( Z )‐ and of −1.79 eV for ( E )‐cyclooctene ( Z and E , respectively). It is concluded that the ‘out of plane’ bending effect in torsioned E does not influence its LUMO‐energy to a larger degree than its HOMO‐energy (as determined by photoelectron ( PE .) spectroscopy) with respect to non‐torsioned Z .
