摘要：

A new high-resolution measurement of the C 1s near-edge photoabsorption spectrum of the ethylene molecule is reported. An analysis of the vibrational structure in the C 1s-pi* band indicates strong excitation of non-totally-symmetric modes and the importance of vibronic coupling. The latter phenomena provides a mechanism for core-hole localization in the final state.
