Knight, L. B.; Wise, M. B.; Childers, A. G.; Davidson, E. R.; Daasch, W. R. The generation and ESR investigation of the BeF radical in rare gas matrices. J. Chem. Phys. 1980, 73, 4198-4198.
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 âˆ¥=2.001, g âŠ¥=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.
