Abstract The He I photoelectron spectra (UPS) of the 2,2′- and 4,4′-bipyridyls and their mono-N-oxides habe been reported and interpreted on the basis of modified CNDO-type calculations. The calculations show that the sequence of the eigenvalues ɛ i is nearly independent from the dihedral angle around the central bond and that the different pattern of the ɛ i must be related to the different positions of the N-atoms. For the N-oxides an assignment is given up to 12eV using the calculated results. Furthermore, the conformations of these compounds has been discussed.
