The book "Quantitative spectroscopy of NMR of natural organic raw materials and products of its processing" under the authorship of G. A. Calabina and his colleagues are a unique publication that opens the door to the world of modern analysis and research of natural organic compounds. This work is not just a training manual, but a whole guide for specialists interested in spectroscopy, chemistry and technologies for processing organic materials. The main theme of the book is the use of nuclear magnetic resonance (NMR) for the quantitative analysis of natural raw materials and their derivatives. The authors consider in detail the methods and approaches that allow to accurately determine the composition and structure of organic substances, which is especially important in the conditions of modern production and ecology. The book presents both the theoretical foundations of NMR and practical examples of its application in various fields, including pharmaceutics, agronomy and environmental studies. This book will be of interest not only to professional chemists and researchers, but also to students studying chemistry, biochemistry and related disciplines. It will be an excellent addition to the teaching materials, allowing a deeper understanding of how modern technologies can be used to analyze natural resources. It will also be useful for environmental and sustainable development professionals who seek to use natural resources more efficiently and minimize their environmental impact. The topics raised in the book cover a wide range of issues, ranging from the basics of NMR to its application in real-world settings. The authors emphasize the importance of accuracy and reliability of the data, which is critical for research and development of new technologies. The book also discusses the influence of various factors on the results of the analysis, which allows readers to better understand how to avoid common mistakes and improve the quality of their research. The writing style of the authors is clear and accessible, which makes complex scientific concepts understandable to a wide audience. G. A. Calabin is a well-known specialist in the field of chemistry, and his previous work is also devoted to the issues of spectroscopy and analysis of organic substances. Readers familiar with his other publications will appreciate the consistency and depth of analysis presented in this book. The book "Quantitative spectroscopy of NMR of natural organic raw materials and products of its processing" will become an indispensable source of knowledge for all who are interested in modern methods of analysis and their application in various fields. It can be useful for both professionals and students seeking to expand their knowledge and skills in chemistry and recycling technologies. If you are looking for information on how modern methods of analysis can help in the study of natural resources, or want to learn about new approaches in the study of organic compounds, this publication will be a real find for you. Do not miss the opportunity to immerse yourself in the world of quantitative spectroscopy and discover new horizons in science and technology!
