Abstract

The symmetry lowering of the highly symmetric spherical top molecule CF4 that belongs to the Td point group, to the C3v symmetrical top, caused by the F1s excitation was discussed. As such, the Doppler splitting of the F1s-1 atomiclike Auger line was observed. Since the shift arises from nuclear motion before Auger decay takes place and fragmentation was initiated on the excited-state potential energy surface, this phenomenon constitutes direct proof that the asymmetric nuclear motion proceeds in the F 1s-excited state, along the direction of the polarization vector of the incident light, leading to symmetry lowering from Td to C3v.
