Abstract

The radical cation, Ph₂PCH₂PPh₂ ⁺˙ has a SOMO which is localised on one phosphorus centre; however, one form of the Ph₂PCH₂CH₂PPh₂ ⁺˙ cation has two equivalent phosphorus nuclei, the unusual form of the e.s.r. spectrum suggesting that the directions of the s–p hybrid orbitals on each phosphorus atom subtend an angle of about 90°.
