Applications of Mössbauer Spectroscopy, Volume I is a collection of essays that discusses the research performed using Mössbauer spectroscopy. The book presents the effect of some stabilizers of polyethylene. It demonstrates the polymerization processes and structure of catalytically active centers. The text also describes the chemical processes in butyl rubber vulcanization. It discusses the experimental studies of iron transport proteins and the thermal decomposition of solids. The section that follows describes the paramagnetic hyperfine structure. The book will provide valuable insights for scientists, chemists, students, and researchers in the field of organic chemistry.
