Notes:
The analysis in part I is generalized to any crystal containing rigid molecules which undergo anisotropic translational and librational motion about a site fixed by symmetry. The treatment is correct to terms in (ui2)2 and (ωi2)2, where (ui2) is the mean-square translational displacement of the molecule along the ith axis and (ωi2) is the mean-square angular libration about the same axis. The first-order treatment to terms in (ui2) and (ωi2) is shown to be equivalent to the rigid-body theory in current use.
