It does not, however, describe specific atomic positions in three-dimensional space, which are considered to be tertiary structure.

Figure 1 shows the general structure, though there are shifts in atomic position that repeat after every three austenitic cells.

By comparison with theoretical curves, these may provide accurate information on atomic positions on the surface at hand.

In its simplest form, non-overlapping spheres are centered on the atomic positions.

The opposite of a single crystal is an amorphous structure where the atomic position is limited to short range order only.

As with all glassy materials, some short-range order can be observed, but there is no long-range pattern of atomic positions.

When viewed altogether, the atomic positions are the same as in lonsdaleite (hexagonal diamond).

Note that the geometries are named according to the atomic positions only and not the electron arrangement.

The new introduction defines "elementary propositions" as atomic and molecular positions together.

In contrast, in an amorphous structure the order in atomic positions is limited to short range.
