Sommerfeld Atomic Struct. & Spectral Lines vi. 364 If we wish to exclude the forbidden lines by a principle of selection, we must..introduce a new quantum number; we call it the inner quantum number and designate it by ni. 1926 Proc. Royal Soc. A. 111 84 Each term..in general will be a multiple term consisting of several members with different values of the ‘inner quantum number’ j. 1967 W. R. Hindmarsh Atomic Spectra ii. 18 The regularities of the multiplet structure of spectra were considered in some detail by Sommerfeld... He introduced an ‘inner’ quantum number to distinguish the various states of a multiplet, and suggested that it may be connected with a property of the electrons in inner shells (the core electrons). The true explanation of the doublet structure of the terms of alkali metal atoms is provided by the concept of electron spin. < as lemmas |
