Figure 6
(a) Propane thermal expansion tensor representation surface at 80 K, indicating the principal directions α₁ and α₂ (α₃ is parallel to the b axis by symmetry) and the magnitude of the thermal expansion with direction by colour coding of the surface. (b) Slices through the tensor representation surface at 20 K intervals, revealing the very slight changes in orientation of the principal directions. Note that the directions of greatest and intermediate expansion, α₁ and α₂, reverse at low temperature.
