The tetraethylammonium salt of the transition-metal complex FeCl4 − has been examined using inelastic X-ray scattering (IXS) with 1.5 meV resolution (12 cm −1 ) at 21.747 keV. This sample serves as a feasibility test for more elaborate transition

The vibrational spectrum of an η[superscript 1],η[superscript 1]-1,2-peroxodiiron(III) complex was measured by nuclear resonance vibrational spectroscopy and fit using an empirical force field analysis. Isotopic 18O2 labelling studies revealed a fe

Normal coordinate calculations, producing synthetic infrared and Raman spectra, were carried out on melilites, pyroxenes, silica polymorphs and feldspars. Atomic motions are complex in the high-frequency Raman modes of melilites and aluminous pyroxen

A complete description of the optical spectra of a mineral should include specification of the (mutually perpendicular) principal directions of absorption — greatest, intermediate, least — for each important absorption band. In monoclinic and tri

Extraterrestrial calcium phosphates (“whitlockites”) have the anhydrous β-Ca3(PO4)2 structure, which is different from that of hydrous terrestrial whitlockite. This has been confirmed by X-ray refinement of the structure of a phosphate from the
