Core excitation in O-3 localized to one of two symmetry-equivalent chemical bonds: Molecular alignment through vibronic coupling
Core excitation from terminal oxygen O-T in O-3 is shown to be an excitation from a localized core orbital to a localized valence orbital. The valence orbital is localized to one of the two equivalent chemical bonds. We experimentally demonstrate this with the Auger-Doppler effect which is observable when O-3 is core excited to the highly dissociative O(T)1S(-)17a(1)(1) state. Auger electrons emit
