Infrared Spectra of the Crystalline Inorganic Borates
Abstract:
Infrared absorption spectra of anhydrous, crystalline, inorganic borates were obtained in the 2000 cm-1 to 300 cm-1 range. Compounds with B10 and B11 isotopes were prepared to assist interpretation. Spectral bands for all orthoborates and pyroborates and some metaborates could be assigned satisfactorily. Borates with complex ring-type anions generally exhibited spectra of such complexity that only superficial interpretation was attempted. From correlations between spectra and structure it appears that boron in 3-fold or in 4-fold coordination can be identified with reasonable assurance on the basis of the infrared spectrum alone. Absorption bands are tabulated for about 80 borates and typical spectra are shown.

Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...
