Anisotropic ultrafast dissociation probed by the Doppler effect in resonant photoemission from CF/sub 4/
Phys. Rev. Lett. 90(23), 233006 (2003).

Abstract
The resonant Auger spectrum from the decay of F 1s-excited CF/sub 4/ is measured. Several lines exhibit a nondispersive kinetic energy as the exciting photon energy is tuned through the resonance region. The F 1s/sup -1/ atomiclike Auger line is split into two components due to the emission of Auger electrons by a fragment in motion, when electron emission is observed along the polarization vector of the light. This Doppler splitting is direct evidence that the core excitation leads to T/sub d/ to C/sub 3v/ symmetry lowering, by elongation of a specific C-F bond preferentially aligned along the polarization vector of the incident photon
