Sažetak
The infrared spectra of an amorphous, rather unstable form of calcium carbonate has been obtained in the region 4000-400 cm-1 and at the temperature of liquid nitrogen. In addition the IR spectra of the crystalline polymorphs (vaterite, aragonite and calcite)have been measured on powders with higher resolution and precision than previously, in the region 4000-200 cm-1 without cooling and in the region 4000-400 cm-1, cooling the samples by liquid nitrogen.
