Single-crystal infrared reflectance spectrum of potassium tetraoxochromate(VI), and a new reflectance accessory

Abstract

The complete i.r. reflectance spectrum of potassium tetraoxochromate(VI) has been observed and analysed by the Kramers–Kronig method. All of the observable bands are assigned to their symmetry species. Together with previously reported single-crystal Raman data, this completes the assignment for this complex. The design of a near-normal-incidence reflectance accessory for the Perkin-Elmer 225 spectrometer is also described.
