N2 - High-resolution photoabsorption spectra of CO and NO below the O [Formula Presented] ionization threshold are presented. The vibrational fine structure of the O [Formula Presented] and O [Formula Presented] Rydberg excitations could be resolved for both molecules, allowing a determination of the vibrational energies and intramolecular distances of the core-excitation states in CO and NO from Franck-Condon analyses. Ab initio calculations are performed for the O [Formula Presented] excitation in CO to give an independent confirmation of the spectroscopic parameters derived from the Franck-Condon analysis. The spectral features of the O [Formula Presented] Rydberg region in CO are reassigned on the basis of the experimental results. The results obtained for the O [Formula Presented] Rydberg state in NO support the idea of a weakening of the molecular bond upon an O [Formula Presented] ionization process.
