| 释义 | > as lemmasorbital angular momentum quantum number   orbital quantum number  n. Physics (more fully  orbital angular momentum quantum number) the quantum number of the angular momentum possessed by an electron or group of electrons by virtue of occupying a particular orbital (symbol l or L; see L n. 6b); also called azimuthal quantum number. ΚΠ 1929    Proc. Royal Soc. A. 124 170  				The general theory must hold for the first approximation, and can therefore be expressed in terms of the orbital quantum numbers. 1949    Proc. Royal Soc. A. 196 138  				As S = 0, J = l the orbital angular momentum quantum number, which is thus a true quantum number for the singlet states. 1994    D. F. Shriver  et al.  Inorg. Chem. 		(ed. 2)	 i. 19  				Each subshell of a shell is distinguished by a quantum number l called the orbital angular momentum quantum number. < as lemmas |
