Abstract
The spectroscopist regards energy sources as indispensable to the functioning of a variety of spectroscopic instruments, and also in themselves as sources of information on atomic and molecular behaviour. Types of source, and their applications, are surveyed in the light of this duality of interest. Attention is drawn to recent developments such as isotope lamps, hollow cathode lamps and radio-frequency excited sources, that have been important enough to merit commercial exploitation.
