If, in Figure 3.3, P and P are a distance df apart then the linear dispersion is defined as df/dl whereas the angular dispersion is defined as AO/AX, where 6 is the angle shown. 

The quantum generalization of the APR Hamiltonian results after supplementing this classical Hamiltonian with a non-commuting angular momentum part [Lj, p] = -ihSji which introduces quantum dispersion and thus qualitatively new effects due to additional fluctuations and tunnehng. 

The case of water is particularly convenient because the required high Ka states may be detected in the solar absorption spectrum. However, it is difficult to observe the necessary high vibrational angular momentum states in molecules, which can only be probed by dispersed fluorescence or stimulated emission techniques. On the other hand, it is now possible to perform converged variational calculations on accurate potential energy surfaces, from which one could hope to verify the quantum monodromy and assess the extent to which it is disturbed by perturbations with other modes. Examples of such computed monodromy are seen for H2O in Fig. 2 and LiCN in Fig. 12. 

The pure ceria films were textured with out-of-plane (Aco) and in-plane (A) mosaic dispersions as low as 3.8° (Fig. 7.15a) and 6.1 ° (Fig. 7.15b), respectively. Although the out-of-plane angular dispersion increased from 3.8° to 5.10 when Sm doping was increased, a significant improvement was achieved in both out-of-plane and in-plane texture when compared with the Ni-based substrates i.e., Aco = 7.9° and A = 7.6° (Fig. 7.16). 

Angular distribution, dispersion and relative fluctuation of the temperature of the relic radiation ((Jumaev, 2004)) is found.
