Over the last 30 years, Dr. Nikita V. Chukanov has collected IR spectra ofabout2000mineral species,including247holotype samples.Inthisbook, he presents3309 spectra of theseminerals with detailed description and analyticaldataforreference samples.Inthecourseof this work, about 150 new mineral species have been discovered. After an introductory chapter, infrared spectra of minerals are given together with the descriptions of standard samples used (occurrence, appearance, associated minerals, empirical formula etc.) and some comments. Sections are organized according to differentclassesofcompounds(silicates,phosphates, arsenates, oxides etc.).
