Preferred Label : diffusional transition;
IUPAC definition : A transition that requires the rearrangement of atoms, ions or molecules in a manner
that cannot be accomplished by a cooperative atomic displacement; it may require the
movement of atoms, ions or molecules over distances significantly larger than a unit
cell. Example: The transition of graphite (hexagonal sheets of three-coordinated carbon
atoms) to diamond (infinite three-dimensional framework of four-coordinated carbon
atoms) at high temperature and pressure.;
