WebMar 8, 2016 · The crystallographic axes are used mainly by crystallographers. These axes are similar to the geometric axes and are used for plotting the orientations of faces and symmetry elements in crystals. It is important to know that it is not vital that the crystallographic axes should be part of symmetry of the crystals. WebAug 28, 2024 · Rotating about a non-crystallographic axis along a B-F bond. The most common case of disorder is a rotation about an axis, the simplest of which involves a non-crystallographic symmetry related rotation axis about the vector made by one of the B-F bonds; this operation leads to three of the four F-atoms having two site occupancies … cynthia baxter fantastic fiction

Depending upon the crystal system, these axes are not necessarily orthogonal nor of equal length, … WebMar 27, 2024 · The <010> axis forms a more diffuse point maxima, at approximately 90° to the <100> axis. The <001> axis forms a weak girdle maxima (where <001> data points lie on a great circle when plotted on lower hemisphere, equal area plots) where <001> is oriented in the ENE–WSW plane relative to reference frame of Figure 2 (Figure 3). WebMore than one kind of crystal system has a single axis of high symmetry (threefold, fourfold or sixfold). The anisotropy of such crystals is called uniaxial anisotropy.
