2. IR Spectra of Minerals and Related Compounds, and Reference Samples’ Data

This chapter contains IR spectra of mineral species and varieties, most of which was not included in the preceding reference book (Chukanov in Infrared spectra of mineral species. Springer, Dordrecht 2014a). Along with spectra obtained by us, we provide the most reliable data on the infrared spectra of minerals published elsewhere during the last 60 years. Each spectrum is accompanied with analytical data on the reference sample, its occurrence and general appearance, associated minerals, as well as kind of sample preparation and/or method of registration of the spectrum. In addition, we provide IR spectra of some synthetic compounds which are chemically or structurally related to any known minerals or may be hypothetically considered as synthetic analogs of potentially new mineral species.
