The 13 electron BeF radical has been generated and trapped in argon and krypton matrices at 12 K and studied via ESR spectroscopy. 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/sub parallel/=2.001, g/sub perpendicular/=2.001, A/sub iso/(Be)=294(2) MHz, and A/sub iso/(/sup 19/F) =230(2) MHz. The /sup 19/F hfs is unusually isotropic for an MF radical, suggesting that rotational averaging might be occurring. Results of ab initio theoretical calculations are compared to the observed A tensors. The BeF molecule was generated by the codeposition of thermally produced Be atoms and molecular fluorine in the rare gas matrices.
