The orientation of molecules in solutions can be achieved by two approaches; using already oriented medium(liquid crystals, solution of aligned nanorods or nanodiscs) as a solvent where dissolved molecules of interest align by the physical interaction(steric, electrostatic, etc.) with the elements of media; or by directly aligning molecules, if they have large anisotropy of one of their own physical properties(magnetic, electric, steric, etc.).  1, fiche 1, Anglais, - oriented%20medium

… an independent determination of molecular magnetic susceptibility anisotropy can be used to reduce the number of parameters that must be taken from residual dipolar measurements in the determination of structure or motion … For magnetic field alignment of diamagnetic systems, susceptibility tensors can be calculated from the summation of individual group anisotropies when a structural model for the molecule is available.  1, fiche 2, Anglais, - molecular%20magnetic%20susceptibility%20anisotropy

Users of permanent magnets know of the very high magnetic coercivity exhibited by certain rare earth-iron alloys, most commonly neodymium-iron-boron... but also including such other rare earth elements as dysprosium for higher anisotropy... Very similar alloys have been developed which excel in related magnetic properties. Take for example, the alloy with terbium and dysprosium commonly known as Terfenol-D... which exhibits a very high magnetostriction; this alloy is said to have "Giant" Magnetostriction.  2, fiche 3, Anglais, - Terfenol%2DD

... a miniature actuator ... utilizes a Terfenol-D rod; only the end of the rod is visible, attached to a metal dome for actuation. The length of the rod changes as current is applied to the coil surrounding it. The housing acts as part of the magnetic circuit, which also includes a conventional permanent magnet for biasing (not visible). Thus, actuation is provided only by the changing length of the rod, although some mechanical amplification (e.g.: using a lever arm) may be advantageous.  2, fiche 3, Anglais, - Terfenol%2DD

Le Terfenol-D, alliage de métaux de faible résistance électrique, développe des courants de Foucault lorsque la fréquence de vibration augmente, d'où des pertes. [...] Autre inconvénient du Terfenol-D : son coût élevé, obstacle qui pourrait être surmonté grâce à des alliages à base de terres rares moins chères.  1, fiche 3, Français, - Terfenol%2DD

... the dependence of the chemical shift on the geometric relationship between that local environment and the direction of the static magnetic field... This... factor is referred to as the chemical shift anisotropy(CSA). The net result of the CSA is that, for a static amorphous or powdered crystalline sample, the entire range of the chemical shifts spanned by all possible orientations is present in the spectrum. The result is known as a CSA powder pattern...  1, fiche 5, Anglais, - chemical%20shift%20anisotropy
