    Notes: Abstract We have investigated Czochralski-grown manganese-doped AlSb by low-temperature photoluminescence spectroscopy. Discrete donor-acceptor pair lines are resolved, which involve the Mn acceptor. A Mn acceptor binding energy (E A =92±5 meV) is deduced from the donor-acceptor pair luminescence.

    Notes: Summary Quantum chemical calculations based on density functional theory have been performed on Cr(CO)6, (η6-C6H6)Cr(CO)3 and (η6-C6H6)Cr(CO)2(CS) at the local and nonlocal level of theory using different functionals. Good agreement is obtained with experiment for both optimized geometries and metal-ligand binding energies. In particular, a comparison of metal-arene bond energies calculated for the (η6-C6H6)Cr(CO)3 and (η6-C6H6)Cr(CO)2(CS) complexes correlates well with kinetic data demonstrating that substitution of one CO group by CS leads to an important labilizing effect of this bond, which may be primarily attributed to a larger π-backbonding charge transfer to the CS ligand as compared with CO.

    Notes: Summary.  Quantum chemical calculations based on density functional theory have been performed on Cr(CO)6, (η6-C6H6)Cr(CO)3 and (η6-C6H6)Cr(CO)2(CS) at the local and nonlocal level of theory using different functionals. Good agreement is obtained with experiment for both optimized geometries and metal–ligand binding energies. In particular, a comparison of metal–arene bond energies calculated for the (η6-C6H6)Cr(CO)3 and (η6-C6H6)Cr(CO)2(CS) complexes correlates well with kinetic data demonstrating that substitution of one CO group by CS leads to an important labilizing effect of this bond, which may be primarily attributed to a larger π-backbonding charge transfer to the CS ligand as compared with CO.
