Le principe de la résonance magnétique repose sur le fait que lorsqu'un moment magnétique situé dans un champ magnétique est soumis à une excitation magnétique périodique, son comportement n’ est influencé par l'excitation que si celle-ci à une fréquence bien déterminée. Cette perturbation affecte le comportement électromagnétique de l'échantillon étudié et peut être mesurée. On obtient alors une courbe de variation appelée raie de résonance. La mesure directe de la résonance magnétique a été améliorée à l'occasion des études sur les radars pendant la Seconde Guerre mondiale. 6, record 10, French, - moment%20magn%C3%A9tique

Un bon exemple d’un matériau magnétique désordonné est fourni par l'alliage dilué cuivre-manganèse, noté CuMn, où des atomes de manganèse, porteurs de moment magnétique(qui constitue en quelque sorte un aimant élémentaire), sont dispersés au hasard dans une matrice de cuivre qui est elle-même non magnétique. Peu importent ici les détails de fabrication métallurgique [...] l'important est que les atomes magnétiques soient répartis de manière aléatoire, et qu'ils ne puissent plus changer de site, une fois l'échantillon formé. Il s’agit d’un désordre figé. 1, record 16, French, - mat%C3%A9riau%20magn%C3%A9tique%20d%C3%A9sordonn%C3%A9

The most important consequence of the extraordinary sharpness of nuclear magnetic resonance (NMR) lines in liquids, caused by motion narrowing, is the possibility of measuring the chemical shifts; that is, the separation between NMR lines from nuclear spins of the same species but in different molecular environments. 2, record 18, English, - chemical%20shift
Record number: 18, Textual support number: 2 CONT
The extensive use of NMR in molecular structure determinations arises from the slight shift in the resonance frequency of an atom - commonly that of a proton - due to the environment of neighboring atoms. Because the magnitude of this shift depends on the type of environment, it is called the chemical shift. 3, record 18, English, - chemical%20shift

Résonance magnétique nucléaire(R. M. N.). Les spectres de résonance nucléaire mettent en évidence les différences d’énergie des spins nucléaires des molécules en présence d’un champ magnétique. Les raies spectrales correspondantes qui se trouvent dans le domaine hertzien pour des champs de quelques milliers de gauss permettent d’atteindre deux grandeurs moléculaires importantes : les déplacements chimiques(...) qui sont dus à la création de champs magnétiques locaux, légèrement différents du champ magnétique appliqué, liés au moment diamagnétique induit de la molécule. La méthode est très sensible à de toutes petites modifications de ce champ local, de telle sorte que les raies de résonance de chaque noyau dépendent fortement de leur environnement chimique. 2, record 18, French, - d%C3%A9placement%20chimique
