Photolytic codeposition generation of the HgF radical in an argon matrix at 12 K: An ESR investigation

The HgF radical has been generated by photolysis during the codeposition reaction of Hg atoms and F2(g) in an argon matrix at 12 K. The magnetic parameters are g(∥) = 1.993(1), g⊥ = 1.961(1); A∥ (19F) = 1344(10) MHz, A⊥ (19F) = 195(5), A∥ (199Hg) = 22 622(10), A⊥(199Hg) = 21 880(8), A∥ (201Hg) = 8055(12), A⊥ (201Hg) = 7760(10). Utilizing the g and A tensor data, the electronic structure of HgF is compared to the other MF radicals studied.
