Abstract

The ZnP, Z67nP, CdP, C111dP, and C113dP radicals have been formed by laser ablation of the metal with GaP pressed into the metal surface, isolated in an inert neon matrix at 4.3 K and their electronic structure was established using electron spin resonance spectroscopy. The following magnetic parameters were determined experimentally for ZnP/Z67nP, g⊥=1.9982(2), A⊥(P)=111(6) MHz, A⊥(Z67n)=160(2) MHz, and D=−29 988(3) MHz and estimates were made for the following ZnP/Z67nP magnetic parameters: g∥=1.9941(2), A∥(P)=−5(6) MHz, and A∥(Z67n)=180(50) MHz. The following magnetic parameters for CdP/C111dP/C113dP were determined experimentally: g⊥=1.9963(2), A⊥(P)=97(3) MHz, A⊥(C111d)=862(3) MHz, and A⊥(C113d)=902(3) MHz. Evidence for the formation of the MgP radical was also obtained and an approximate hyperfine coupling constant of A⊥(P)=157(6) MHz was determined. The low-lying electronic states of ZnP and MgP were also investigated using the multiconfigurational self-consistent field technique. Potential energy surfaces, binding energies, optimized bond lengths, energy separations, and dissociation energies have been determined. Both radicals are found to have 𝛴4− ground states with a leading configuration at re of 10𝜎211𝜎25𝜋15𝜋112𝜎1 for ZnP and 7𝜎28𝜎23𝜋13𝜋19𝜎1 for MgP. Significant mixing to this state is calculated for MgP.
