We hope it provides an up-to-date overview which postgraduates, advanced undergraduates, and professionals in astrophysics can use as a "reference of first resort" before going on to read the more specialist monographs or

The Saha equation describes a different equilibrium from the coronal approximation because in LTE, the excited states are all populated according to Boltzmann’s law. These excited states play an important role in determining the ionization state of the medium.

Nevertheless, electrons can still make transitions between these free states, known as free-free transitions, or between bound atomic levels and free states, known as bound-free or free-bound transitions. In this nomenclature, the line transitions discussed so far are bound-bound transitions.

If not, the reader is referred to the highly readable account of this and other topics in modern physics which is in the book by Rohlf (1994). Also, a lucid introduction to molecular spectroscopy is given by Atkins (1983); see notes on this chapter.
