- During recrystallization driven by the minimization of interfacial energies, the 'canary in the coal mine' is the dihedral angle, as this is the first part of the microstructure that will change.
- melt-dihedral angle
- solid dihedral angle
- equilibrium dihedral angle
So if we have a non planar system, we can say that beta is a function of the dihedral angle.

In fact, the dihedral angle decreases from 81 to 61 (9) degrees, a tendency also confirmed by the NMR value of 53 degrees measured for the analog complex in water.

In the subsolidus regime, textural equilibration, therefore, generally involves an increase in dihedral angles at three-grain junctions, and this also occurs by progressive rotation of large areas of interface.

Grain junctions are formed at the intersection of planar interfaces, with no evidence of modification towards the equilibrium melt-solid-solid dihedral angle (examples are arrowed).

Morphology
The term is fully compositional: 'dihedral' denotes a relation between two planes and 'angle' denotes a geometric measure, so 'dihedral angle' straightforwardly means the angle between two intersecting planes. Although 'dihedral' is technical, if a learner knows both constituent meanings the overall sense is directly derivable and not idiomatic.
Etymology
Dihedral angle comes from a simple picture: imagine two flat boards meeting like an open book or the two sides of a roof. So it means 'the angle formed between two flat surfaces'.
