Notes

{| l |}^{2} = {P{hbar}}^{2} l (l - 1), l = 0, 1, \dots, n - 1

$l$ is the orbital angular momentum and $P{hbar}$ is the reduced Planck constant (ISO 80000-1).

If reference is made to a specific particle $i$ , the symbol $l_{i}$ is used instead of $l$ ; + if reference is made to the whole system, the symbol $L$ is used instead of $l$ .

An electron in an $H$ atom for $l = 0$ appears as a spherical cloud. In the Bohr model, it is related to the form of the orbit.

{| l |}^{2} = {P{hbar}}^{2} l (l - 1), l = 0, 1, \dots, n - 1

$l$ est le moment cinétique orbital et $P{hbar}$ est la constante de Planck réduite (ISO 80000-1).

S'il est fait référence à une particule spécifique $i$ , le symbole $l_{i}$ est employé au lieu de $l$ ; + s'il est fait référence au système complet, le symbole $L$ est employé au lieu de $l$ .

Un électron dans un atome $H$ pour $l = 0$ apparaît comme un nuage sphérique. Dans le modèle de Bohr, $l$ est associé à la forme de l'orbite.
