ABSTRACT The HeI photoelectron spectra of the isoelectronic molecules, cyanogen azide, NCN3, and cyanogen isocyanate, NCNCO have been studied in detail. As expected the spectra are quite similar, however it is in the way in which they differ that the interest in the analysis lies. The molecules are both V-shaped but differ in that the angles at the middle N atom are 120° in NCN3 and 140° in NCNCO. The combined study yields a good understanding of how photoelectron bands associated with orbitals, which in a linear configuration are degenerate, behave as the bending angle increases.
