Considera un electrón en un átomo de hidrógeno. Como ya hemos visto, el movimiento del electrón a través del espacio es parametrizado por los tres números cuánticos $n$ , $l$ , y $m$ . (Ver Sección [s10.4].) A estos debemos ahora sumar los dos números cuánticos $s$ y $m_s$ que parametrizan el movimiento interno del electrón. (Véase el capítulo anterior.) Ahora, los números cuánticos $l$ y $m$ especifican el vector de momento angular orbital del electrón ${\bf L}$ ,, (tanto como se puede especificar) mientras que los números cuánticos $s$ y $m_s$ especifican su vector de momento angular de giro, ${\bf S}$ . Pero, si el electrón posee tanto momento orbital como angular de espín entonces, ¿cuál es su momento angular total?
