The electron donor and acceptor properties of PF 3 are investigated theoretically by ab initio SCF MO calculations of PF 3O. The results are used to discuss the photoelectron spectra of PF 3 and PF 3O, reported here, and the change in ligand geometry on co-ordination....
This bond angle is derived by determining the molecular geometry at the central atom, which depends on the distribution of valence electrons here. According to VSEPR theory, different bonding and non-bonding valence electron pairs will spread out in three-dimensional space to minimize repulsion....
