- 14.1: The Harmonic Bath Hamiltonian
- The dynamics of the "bath'' or environment chemical reactions is often less interesting than reaction coordinates, but still must be accounted for in some manner. A model that has maintained a certain level of both popularity and success is the so called "harmonic bath'' model, in which the environment to which the special degree(s) of freedom couple is replaced by an effective set of harmonic oscillators.
