摘要：
We compare mid- and far-infrared attenuated total reflectance spectra for calcite and aragonite, which are two polymorphs of calcium carbonate, CaCO3, in order to demonstrate which spectral feature changes can be attributed to phase (crystal structure) differences. These comparisons, together with our recent studies of multi-phase carbonate-containing samples, help to lay the groundwork for distinguishing far-infrared spectral features that are related to crystallinity differences in calcium carbonates.
