摘要：

The C 1s and O 1s photoelectron spectra of the CO molecule have been measured with high resolution. The vibrational spacing of the O 1s(-1) state (226 +/- 7 meV) is significantly lower than in the C 1s(-1) state and in the molecular ground state. Compared to the groundstate equilibrium C-O distance of 1.128 Angstrom, we extract from the analysis of the Franck-Condon factors bond lengths of 1.079(2) Angstrom and 1.167(4) Angstrom for the C 1s and O 1s core-ionized states, respectively.
