Abstract:
Tungsten (VI) hexachloride, WCl6, and tungsten (VI) oxytetrachloride, WOCl4, are of interest in a variety of technological applications. In the present work, complete vibrational assignments are provided for both molecules in the "free" state (i.e., in the gas phase or in solution) and in the solid state. The first inelastic neutron scattering spectra of both molecules in the solid state are recorded. The assignments are supported by density functional theory calculations. In all cases, the W-Cl stretching modes occur in the 300-400 cm-1 range, and the Cl-W-Cl bending modes in the 100-250 cm-1 range.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
