Role of Energy in Reactive Molecular Scattering: An in Form a Tion-Theoretic Approach

摘要: Publisher Summary This chapter discusses the role that information–theoretic methods have played in dealing with reactive molecular scattering. The approach has made possible compaction of data fields beam kinetics, chemiluminescence, and chemical lasers. surprisal analysis vibrational population inversions often leads to a one-parameter description disequilibrium fast exoergic elementary reactions. is importance characterizing gain Another practical application evaluation entropy cycle involved operation maser or laser. However, most fundamental simplification severely non-Boltzmann state distributions. key concept surprisal, deviation from expectation on basis microcanonical equilibrium. Clearly less structured function classical energy variable than populations themselves; hence advantage present nonequilibrium processes, including distributions product branching ratios.
