This volume is the third and final part of the series of reference books on vibrational spectra of minerals. Unlike the two previous parts (Chukanov
2014; Chukanov and Chervonnyi 2016), this book contains not only infrared
(IR) spectra of minerals but also data on their Raman spectra.
In Chap. 1, numerous examples of the application of 1R spectroscopy to the analysis of crystal-chemical features of minerals are considered. In particular, spectral bands that characterize different local situations around OH- and Bo/- groups in vesuvianite-group minerals are revealed. The effect of symmetry on the parameters of 1R spectra of vesuvianite-group minerals is discussed. By means of1R and Raman spectroscopic methods, it is shown that the clathrate mineral melanophlogite is not a single species but a mineral group including minerals with different combinations of small molecules (C02, CH4, H2S, N2, H20, C2H6) entrapped in structural cages. Based on numerous 1R pectra of nakauriite samples from different localities, it is demonstrated that this mineral does not contain sulfate groups, and its tenta• tive simplified formula (Mg3Cu2+)(0H)6(C03)-4H20 is suggested. A close crystal chemical relationship between nepskoeite and shabynite is demonstrated based on their 1R spectra, compositional, and X-ray diffraction data. Contrary to the formula Mg4Cl(OH)?-6H20 accepted for nepskoeite, this mineral is a borate with the tentative simplified formula Mg5(B03)(CI,
OHh(OH)s-nH20 (n > 4). Consequently, shabynite may be a product of
nepskoeite dehydration. Based on 1R spectroscopic data, it is also shown that some nominally boron-free lead carbonate minerals (molybdophyllite, hydrocerussite, plumbonacrite, somersetite) often contain minor Bo/• admixture which is overlooked in structural and chemical analyses.
Chapter 2 contains 1R spectra of 1024 minerals and related compounds which were not included in the preceding reference books of this series (Chukanov 2014; Chukanov and Chervonnyi 2016). Most spectra are accompanied by the information about the origin of reference samples, methods of their identification, and analytical data.
