Near- and mid-infrared spectral studies of minerals are reviewed. Single-crystal anisotropy measurements provide information about: cation site occupancy in orthopy­ roxenes; Fe2+/Fe3+ zonation in clinopyroxenes; water molecules in cordierite, and metamictization and water content of zircon. Studies of manganese oxides identify mineralogy in sub-microcrystalline minerals and provide structural information about disordered oxides and their water content.
