31. It is often used to understand macromolecular orientation in crystal lattices , liquid crystals or polymer samples. 32. Substitutional lattice diffusion is often contingent upon the availability of point vacancies throughout the crystal lattice . 33. The charge carrier exchanges energy with one of the polar optical modes of the crystal lattice . 34. In a crystal lattice vibration, atomic positions vary. 35. Pink and red are caused by plastic deformation of the crystal lattice from temperature and pressure. 36. At absolute zero temperature, a crystal lattice lies in its ground state, and contains no phonons. 37. Rather, the hole spans an area in the crystal lattice covering many hundreds of unit cells. 38. Hydrogen solubility in metals is influenced by local distortions or impurities in the metal crystal lattice . 39. Bragg diffraction occurs on the atomic crystal lattice . 40. They are caused by hopping of Na ions among interstitial sites of the NASICON crystal lattice .
