The theory of observed spectra that give less than the theoretical number of transitions, i.e. apparently simple spectra, is studied. The general conditions for the existence of such spectra of the type A m * B n *… R p * X q *… are discussed in terms of effective L ARMOR ‐frequencies. Explicit experimental conditions for which observed spectra are apparently simple are given for spectra of the type A n * BX q *as well as A 2 B 2 X.
