2.3 Graphical representations of the Gaussian mean-square displacement matrix

Just as interatomic distances in crystals are most conveniently discussed in terms of atomic coordinates such as tex2html_wrap_inline2748 with dimension length rather than in terms of the dimensionless components tex2html_wrap_inline2750, the physical interpretation of atomic displacement parameters is most convenient in terms of the mean-square displacement matrices U with elements having dimension (length)2.
