Infra-red spectra of anhydrous molybdates and tungstates

Abstract

The infra-red spectra of 19 molybdates and 18 tungstates have been measured from 4000 to 250 cm⁻¹. The identity of the samples was confirmed by X-ray powder diffraction. The spectra are generally sufficiently individual in detail to permit identification of the particular substance. The results are discussed in terms of the site symmetry of the anionic group.
