Abstract

The 13 electron BeF radical has been generated and trapped in argon and krypton matrices at 12 K and studied via ESRspectroscopy. Comparisons are made between BeF and other similar radicals. The calculated dipole moment for BeF is 1.1 D. The magnetic parameters in argon are g ∥=2.001, g ⊥=2.001, A iso(Be)=294(2) MHz, and A iso(19F) =230(2) MHz. The 19F hfs is unusually isotropic for an MF radical, suggesting that rotational averaging might be occurring. Results of a b i n i t i o theoretical calculations are compared to the observed Atensors. The BeF molecule was generated by the codeposition of thermally produced Be atoms and molecular fluorine in the rare gas matrices.
