Over the last 30 years, Dr. Nikita V. Chukanov has collected IR spectra of about 2000 mineral species, including 247 holotype samples. In this book, he presents 3309 spectra of these minerals with detailed description and analytical data for reference samples. In the course of this work, about 150 new mineral species have been discovered. This book presents spectra of each mineral together with a description and comments on standard samples used (occurrence, appearance, associated minerals, empirical formula etc.). Sections are organized according to different classes of compounds (silicates, phosphates, arsenates, oxides etc.).
