We have measured the vibrational fine structure in the electronic decay spectrum of the N 1s..-->..1..pi../sub g/ core electron excited state in molecular nitrogen. The Franck--Condon analysis of the vibrational substructure shows that within the 10/sup -14/ s lifetime of the core hole excited state the molecule adjusts to the excited state configuration, characterized by a change in bond length by 0.071 A. Interference effects due to the short lifetime of the intermediate state play only a minor role.
