Approximate normal-coordinate calculations in the vibrational spectroscopy of metal cluster complexes
Autor: Ian A. Oxton
Publikováno v: Journal of Molecular Structure. 79:243-246
The force constant associated with the short Os-Os separation in the metal cluster complex (μ 2 -H) 2 Os 3 (CO) 10 has been estimated as 199 N m −1 . It is shown that this value represents the effect of the bridging Os-H bonds along the Os-Os vect

Autor: Ian A. Oxton
Publikováno v: Journal of Molecular Structure. 78:77-84
The infrared spectra of a number of metal cluster complexes containing the μ2-bridging carbonyl ligand have been measured, and assignments proposed for the lower-frequency modes of this ligand.

Determination of the molecular symmetry in crystalline germane
Autor: Ian A. Oxton
Publikováno v: Journal of Molecular Structure. 41:195-201
The symmetry of the germane molecule in the various crystalline phases of solid germane has been investigated using the IR spectrum of the isotopically dilute GeH3D molecule. The observed spectra indicate that the cubic crystal symmetry of the higher
