The molecular radical BeCl has been produced by the codeposition of beryllium atoms and chlorine in an argon matrix at 12 K. An ESR investigation yields the following magnetic parameters: g/sub parallel/ = 2.001 (1), g/sub perpendicular/ = 1.998 (1), A/sub parallel/(Be) = 282 (2) MHz, A/sub perpendicular/(Be) = 268 (2) MHz, Vertical BarA/sub parallel/Vertical Bar(/sup 35/Cl) = 53 (2) MHz, and Vertical BarA/sub perpendicular/Vertical Bar(/sup 35/Cl) = 24 (2) MHz. Spin densities obtained from the ESR results are compared with ab initio calculations. The calculations yield a dipole moment of 1.0 D for BeCl. These results for BeCl are compared with BeF, BeOH, and BeH. BeCl, unlike BeF, does not exhibit rotational behavior in an argon matrix.
