Spectral Properties of Anhydrous Carbonates and Nitrates

J. L. Bishop et al.

Summary: The spectral properties of carbonates and nitrates are characterized by specific vibrational bands and absorption features, allowing for their identification on planetary surfaces. Variations in the vibrational absorptions of these minerals are influenced by mineral structure and cation size, resulting in distinct spectral features. Understanding these spectral properties is crucial for remote mapping of carbonate and nitrate chemistry on planetary bodies.
