The asymmetric nuclear motion of the F 1s-ionized state in BF3 was investigated using quadruple-ion-coincidence momentum imaging technique. The charged particles were accelerated by a uniform electrostatic field of ∼20 V/mm along the axis of the three dimensional-time of flight perpendicular to the gas and photon beams. It was found, that the momentum correlation of the four atomic ions departed from one BF4+3 parent molecular ion, produced via multiple Auger decay after F 1s ionization, exhibited asymmetric fragmentation. This asymmetric fragmentation provided proof of symmetry lowering, from D3h to C3v in the F 1s-ionized state.
