The transfonnation matrix L is obtained from a nonnal-mode analysis perfonned in internal coordmates [59, ]. Thus, as the evolution of the nonnal-mode coordinates versus time is evaluated from equation (A3.12.49), displacements in the internal coordinates and a value for q are found from equation (A3.12.50). The variation in q with time results from a superposition of the nonnal modes. At a particular time, the... 

Measurement of the equilibrium properties near the LST is difficult because long relaxation times make it impossible to reach equilibrium flow conditions without disruption of the network structure. The fact that some of those properties diverge (e.g. zero-shear viscosity or equilibrium compliance) or equal zero (equilibrium modulus) complicates their determination even more. More promising are time-cure superposition techniques [15] which determine the exponents from the entire relaxation spectrum and not only from the diverging longest mode. 

If the contribution of the localized eigenfunctions (scars or bouncing ball modes) in (8) is negligible, then all eigenfunctions ipn(x,y) are RGF. The complex coefficients in the superposition, cn, depend on the energy and the coupling between the billiard and leads and are not random as in the Berry function (2). Nonetheless the superposition of RGFs is also a complex RGF (W. Feller, 1971 M.I. Tribelsky, 2002)... 

H 0+C0/Rh(111) produced features analogous to those shown for D20+C0/Rh(lll). A partial superposition of the downshifted CO stretch and the H-O-H scissor mode at 1620 cm-1 makes the effect less welI-resolved for H.O than for D 0, but we in fact observed the CO downshift first witn HgO. 

Let us consider thermal radiation in a certain cavity at a temperature T. By the term thermal radiation we mean that the radiation field is in thermal equilibrium with its surroundings, the power absorbed by the cavity walls, Fa (v), being equal to the emitted power, Pe v), for all the frequencies v. Under this condition, the superposition of the different electromagnetic waves in the cavity results in standing waves, as required by the stationary radiation field configuration. These standing waves are called cavity modes.
