Continuum structured

The first term of Eq. (34) describes a direct transition from the bound state to the scattering projection of the structured continuum. The second term describes a resonance-mediated transition. 

When the variation of Eg 2(E) with energy cannot be neglected, that is, one has a structured continuum, one cannot assume that Aq2( ) vanishes. In such a case.

The situation is quite different for a structured continuum. Consider Fig where the strong-pulse-induced transition to a narrow continuum (Ts = 50 bfi displayed. The results show behavior that is intermediate between a flat , 1 nuum and a discrete set of levels. We see that center-line , caE l — coj <5= 0, ( nuum levels display recurrences, or Rabi oscillations, similar, though not idet...

The primary causes of clathrate formation are geometrical the poor packing of awkwardly shaped hosts, and/or dominant directional host hydrogen bonding (or other interhost attractions), thereby generating void spaces for guest occupancy. Weber and Josel ° have pointed out that there is a structural continuum (1-4) between clathrates on one hand and complexes on the other. 

The nearest intermediate real state is A B and the anticipated final state is B Aj. On the other hand, the alignment of OH(A) fragnents generated through excitation into the structured features associated with I O(C B ) is dramatically reduced, and the reduction is in proportion to the relative contribution "structured continuum in the photofragment fluorescence excitation spearum. Predissociation of H O(C Bi) into OH(A) is only possible when out-qf-plane rotation about the a-inertial axis couples ih structured C state into the B state continmun [44]. This is just the motion necessary to tilt the molecular framewoik away from its initial alignment with respect to and hence reduce the final product rotational alignment - . ... 

Structural studies are best for determining where any given alkene complex lies on the structural continuum between 53 and 5.4. The position of any vinyl protons, or of the vinyl carbon.s in the H and C NMR, also shows a correlation with the structure. For example, at the metalacyclopropanc Xj extreme, the vinyl protons can resonate 5 ppm, and the vinyl carbons 100 ppm to high field of their position in the free ligand, as is appropriate for a change of hybridization from sp- to about SfP at carbon. Coordination shifts are usually much lower in the case of the L extreme.
