As in the case of the teacher, it was also impossible to associate the model of chemical kinetics expressed by the textbook with any one of the historical models. This was because its authors seemed to have developed a completely different model in which they merged characteristics of several distinct historical models treated as if they constituted a coherent whole. For instance, when the authors said that there is a species called an activated complex , they had added elements of the transition state theory to the explanation. However, activated complex and transition state are different concepts, derived from different theoretical backgrounds. Such an absence of... 

This text of the two-volume treatment contains most of the theoretical background necessary to understand experiments in the field of phonons. This background is presented in four basic chapters. Chapter 2 starts with the diatomic linear chain. In the classical theory we discuss the periodic boundary conditions, equation of motion, dynamical matrix, eigenvalues and eigenvectors, acoustic and optic branches and normal coordinates. The transition to quantum mechanics is achieved by introducing the Sohpddingev equation of the vibrating chain. This is followed by the occupation number representation and a detailed discussion of the concept of phonons. The chapter ends with a discussion of the specific heat and the density of states.
