La résonance quadrupolaire nucléaire est basée sur le comportement d’une molécule, contenant un noyau quadrupolaire comme l'azote-14, soumis à un champ radio-fréquence. On appelle noyaux quadrupolaires les noyaux dont le spin est supérieur à 1/2. L'azote-14, naturellement présent à plus de 99 % a un nombre de spin égal à 1 […] Tous les noyaux de spin supérieur à 1/2 sont dits quadrupolaires en raison de la distribution de leurs charges électriques(positives). Contrairement aux noyaux possédant un spin 1/2, cette distribution de charge n’ est plus de symétrie sphérique et peut être schématisée par une ellipsoïde. Il en résulte que le noyau en question porte un moment électrique qui n’ est pas un moment dipolaire mais un moment quadrupolaire qui peut être figuré […] par une répartition de quatre charges ponctuelles, égales deux à deux. 3, record 1, French, - moment%20quadrupolaire

Nuclear magnetic resonance is a consequence of a property possessed by the nucleus known as nuclear spin angular momentum. Some properties associated with nuclear spin angular momentum are similar to those of a spinning macroscopic body, however, nuclear spin angular momentum is a fundamental property that cannot be explained in terms of any other fundamental property such as mass, charge, etc. Nuclear spin angular momentum—like the angular momentum of any other fundamental particle —is a quantized vectorial quantity. Its magnitude is restricted to certain fixed values and its direction is also restricted to certain directions in the presence of a magnetic field. In the absence of a magnetic field, it is not possible to obtain any information regarding its direction. 1, record 3, English, - nuclear%20spin%20angular%20momentum%20vector

C'est une méthode d’étude physico-chimique par résonance très voisine dans son principe de la résonance magnétique nucléaire. Mais les particules dont on veut faire varier le spin ne sont pas les protons mais les électrons de la substance à étudier. Cela veut dire que : 1-la méthode ne sera applicable qu'aux corps possédant un électron célibataire; 2-les énergies mises en jeu sont 1850 fois plus grandes et la résonance aura lieu dans le domaine des ondes centimétriques(UHF). 3, record 4, French, - r%C3%A9sonance%20paramagn%C3%A9tique%20%C3%A9lectronique

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 5, English, - molecular%20entity
