Webb LJ, Rivillon S, Michalak DJ, Chabal YJ, Lewis NS.
PMID: 16599509
J Phys Chem B. 2006 Apr 13;110(14):7349-56. doi: 10.1021/jp054618c.

Transmission infrared spectroscopy (TIRS) has been used to investigate the surface-bound species formed in the two-step chlorination/alkylation reaction of crystalline (111)-oriented Si surfaces. Spectra were obtained after hydrogen termination, chlorine termination, and reaction of the Cl-Si(111) surface with CH(3)MgX...

Theoretical analysis of bonding in N-heterocyclic carbene-rhodium complexes.

Inorganic chemistry

Srebro M, Michalak A.
PMID: 19400577
Inorg Chem. 2009 Jun 15;48(12):5361-9. doi: 10.1021/ic900336r.

The natural orbitals for chemical valence and the Ziegler-Rauk bond energy decomposition analysis were used to describe the donor/acceptor character of the N-heterocyclic carbenes (NHC)-metal bond in two groups of square-planar rhodium(I) complexes: (NHC)RhCl(cod) (1-X; cod = 1,5-cyclooctadiene) and...
