It depends on the context with what degree of precision a molecular entity is to be described. For example, "hydrogen molecule" is an adequate definition of a certain molecular entity for some purposes, whereas for others it is necessary to distinguish the electronic state and/or vibrational state and/or nuclear spin, etc. of the hydrogen molecule. 1, record 1, English, - molecular%20entity

La façon dont une entité moléculaire doit être décrite dépend du degré de précision qu'il est nécessaire d'atteindre selon le contexte. Par exemple, l'expression «molécule d'hydrogène» est suffisante dans certains cas pour définir une entité moléculaire; par contre, dans d'autres contextes, il est nécessaire de préciser l'état électronique, l'état vitrationnel, le spin nucléaire, etc. 1, record 1, French, - entit%C3%A9%20mol%C3%A9culaire
