The fragmentation of core-excited BF 3 has been studied by means of partial cation and anion yield measurements around the B and F K edges. All detectable ionic fragments are reported, and differences among fragments are discussed. The observations confirm earlier findings on the dynamics of molecular fragmentation studied by partial ion yields, notably on the influence of Rydberg excitations on fragmentation, the behavior of anion production near threshold, and the importance of intramolecular rearrangement in the formation of F + 2 ions.
