Polar Molecules is a scientific book written by Peter Josef William Debye, which explores the fundamental principles of molecular physics and chemistry. The book is divided into two main sections, the first of which covers the basic concepts of molecular structure and bonding, including the nature of polar molecules and their interactions with other molecules. The second section delves deeper into the physics of polar molecules, discussing topics such as the electric dipole moment, the rotational motion of molecules, and the effects of external electric and magnetic fields on molecular behavior. Throughout the book, Debye employs mathematical models and equations to explain the complex concepts, making it a valuable resource for students and researchers in the fields of molecular physics and chemistry. Additionally, the book includes numerous illustrations and diagrams to aid in the understanding of the material. Overall, Polar Molecules is an authoritative and comprehensive text that provides a thorough exploration of the properties and behavior of polar molecules.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
