Symmetry-adapted form of the Structure Factors


Magnetic Space Group: Fd'd'2 (#43.227) [OG: Fd'd'2 (#43.4.323)]



Values of h, k, l:  h integer, k integer, l integer


Structure factors for general reflections (produced by centrings):


Diffraction vector type:   h,k,l
For  h + k = 2n + 1 or h + l = 2n + 1:      I = 0       F = (0,0,0)
Elsewhere:      I /= 0       F = (Fx,Fy,Fz)


Structure factors for special reflections:

Those diffraction vector types which are fully absent due to the general rule are not listed


Diffraction vector type:   0,0,l
For l = 2:      I = 0       F = (0,0,0)
For l = 4:      I = 0       F = (0,0,Fz)

Diffraction vector type:   0,k,l
For k = 2, l = 2:      I /= 0       F = (0,Fy,Fz)
For k = 2, l = 4:      I /= 0       F = (Fx,0,0)
For k = 4, l = 2:      I /= 0       F = (Fx,0,0)
For k = 4, l = 4:      I /= 0       F = (0,Fy,Fz)

Diffraction vector type:   h,0,l
For h = 2, l = 2:      I /= 0       F = (Fx,0,Fz)
For h = 2, l = 4:      I /= 0       F = (0,Fy,0)
For h = 4, l = 2:      I /= 0       F = (0,Fy,0)
For h = 4, l = 4:      I /= 0       F = (Fx,0,Fz)
