Interaction of Matrix Isolated NiF2 and NiCi2 with CO, N2, NO and 02 and of CaF2, CrF2, MnF2, CuF2 and ZnF2 with CO in Argon Matrices

摘要

The infrared spectra of matrix isolated NiF2 and NiCl2 with CO, N2, NO and 02 and of CaF2, CrF2, MnF2, CuF2 and ZnF2 with CO in argon matrices have been observed. Perturbation of the frequencies of both the small molecules and metal halides are found to occur end these have been tabulated. The perturbed CO frequencies are all above the gas phase frequency. The high-frequency band is correlated to the strength of the electric field of the metal ion at the carbon nucleus. A good correlation is found for the isotropic metal ions while ligand field arguments are involved to explain the deviations for those ions with anisotropic electron distribution.
