Ritz combination principle
- Ritz combination principle
-
the principle that the frequencies of lines in atomic spectra can be represented as differences of a smaller number of terms, all characteristic of the emitting system, interpreted in quantum theory as the emission of exactly one photon in a transition between energy levels. Also called
combination principle.
[
after Walther Ritz (1878-1909), Swiss physicist, who formulated it]
