H = Laue indices h k l of a reflection
K = Laue indices h1 k1 l1 of another reflection
= Bragg angle of a reflection H
IH = intensity of a reflection H ()
FH = the structure factor of H. In this work FH will be corrected for thermal motion and brought onto an absolute scale.
EH = normalised structure factor of H
UH = unitary structure factor of H
GH = structure factor of H based on the squared structure
= phase of reflection H
N = number of atoms in the unit cell
fj = scattering factor of atom j
Zj = atomic number of atom j
rj = position of atom j in vector notation
xj, yj, zj = position of atom j in Cartesian coordinates
E3 = N-1/2|EHEKE-H-K|
E4 = N-1|EHEKELE-H-K-L|
