摘要：

Infrared spectral peak broadening due to atomic disorder and narrowing due to particle-size-related optical absorption effects can be decoupled experimentally and theoretically. Applied to different sources of polycrystalline calcite, the method provides a powerful diagnostic tool for archaeology, geology, and materials/biomaterials science.
