a. Usually italicized. Principal: originally designating one of the four main series (S, P, D, F) of lines in atomic spectra, but now more usually designating electrons, orbitals, etc., possessing one unit of angular momentum (as p-electron, p-orbital, etc.).

1890 J. R. Rydberg in London, Edinb., & Dublin Philos. Mag. 5th Ser. 29 335 A few examples will suffice to show the arrangement and the use of this system. K (D₁, 4) denotes the fourth line of the first diffuse series of the spectrum of potassium..Rb (P₁₂, 2) the second doublet of the principal group of Rb [etc.].

1910 W. M. Hicks in Philos. Trans. (Royal Soc.) (1911) A. 210 97 We recognise four typical sequences, the P, S, D and the new F type.., the fundamental or primitive type.

1922 A. Fowler Rep. Series in Line Spectra iii. 15 Three of the chief series were recognised..namely..Principal, Diffuse, Sharp... Rydberg's names..are conveniently abbreviated to P, D, S.

1964 J. W. Linnett Electronic Struct. Molecules ii. 29 In the oxygen atom two 2p orbitals are half-filled..and so..bonds can be formed to two hydrogen atoms.

1983 G. C. Hill & J. S. Holman Chem. in Context v. 60 Calculations show that the charge clouds for p electrons are not spherical, but approximately ‘dumb-bell’ shaped... In fact, each p sub-shell has three separate p orbitals each of which can hold a maximum of two electrons.
