The C and O 1s photoelectron lines of the CO{sub 2} molecule in the gas phase have been measured with vibrational resolution in the threshold region. The vibrational fine structure on the O 1s line is completely dominated by the antisymmetric stretching mode with a frequency of 307({plus_minus}3)meV . This mode can be excited only via vibronic coupling, as predicted by Domcke and Cederbaum [Chem.Phys.{bold 25}, 189 (1977)], and provides a mechanism for dynamic core-hole localization. Relaxation effects are found to affect strongly the vibrational intensity distribution of the photoelectron line. {copyright} {ital 1997} {ital The American Physical Society}
