Abstract: Both positive and negative phosphrus cluster ions were generated on a homemade laser-probe time-of-flight mass spectrometer. P_6~+ has the highest intensity in positive ion mass spectrum, and P_5~- for negative ions. It is proposed that both P_6~+ and P_5~- adopt the planar monocyclic configuration and are aromatic according to Hückel Rule. Further analysis of mass spectra shows that all cluster anions are composed of 5-membered rings and cations arc composed of 6-membered rings.
