Abstract
Angle-resolved ion yield spectroscopy revealed that ionic fragmentation of a T-d symmetry molecule CF4 is anisotropic following F 1s photoabsorption. The nuclear motion in the Anger-final state resulting in this anisotropic f ragmentation is a consequence of asymmetric nuclear motion or symmetry brea king in the core-excited state, caused by vibronic coupling.
