of (PN)3 are confirmed. The reaction energy ER for the reaction P2+N2⇌PN is determined from extended CPF calculations to be ER=+117±10 kJ/mol, which implies D0(PN)=6.2±0.1 eV. (PN)3 has a D3h planar ring equilibrium structure at the SCF level. Vibrational frequencies of (PN)3 are reported. SCF and CPF treatments show formation of the trimer, 3PN⇌(PN)3, to be exothermic by 334±60 kJ/mol.
