Distance interplanaire (Fr). Distanza interplanare (It). 面間距離 (Ja).


The interplanar spacing or interplanar distance is the perpendicular distance between two successive planes on a family (hkl). It is commonly indicated as dhkl and corresponds to the reciprocal of the length of the corresponding vector in reciprocal space:

dhkl = 1/||r*hkl|| = 1/(hkl)G*(hkl)T

where G* is the metric tensor in reciprocal space and T stands for transposed vector.
