This book concerns the latest achievements in chemical physics and physical chemistry. If we draw a straight line from physics to chemistry, the part of it that is nearer to physics is chemical physics and the part that is nearer to chemistry is physical chemistry. However, there is no pronounced boundary line between these two branches of natural science; everyone sees it in his own way. In the past 40-50 years, one more branch of natural science was shaped at the junction of physics, chemistry, and biology -- biochemical physics. Some questions of biochemical physics are discussed in this book.
