Relaxation and Resonance Absorption

Abstract

In Chaps. 1 and 2 we have treated temporal developments of physical phenomena as stochastic processes, and examined in detail how our understanding of them depends on the degree of crudeness of our description, or in other words, on alterations in the spatial and temporal precision of discernment and also on projections of processes. We have introduced various concepts and physical quantities as tools for our description of phenomena. In and we shall sketch general statistical-mechanical formulations for these physical quantities and the method of their evaluation when atomic structures of substances are assumed.
