Strong coupling complex

Spectroscopic methods naturally focus attention on the distribution of products over internal energy states. It seems clear that virtually every elementary reaction produces products in a non-equilibrium distribution. Even phase space models3, which assume a strong coupling complex in a certain region of phase space, give... 

In the limit of strongly coupled complexes dose to the isergonic region, Ada2 4HDA, and this approximation leads to the qualitative conclusion that AEda and Hda are strongly... 

The CCCC methods for vdW complexes are formulated In both the space-fixed (SF) and the body-fixed (BF) coordinates. The SFCCCC method Is more appropriate for the treatment of weak-coupling complexes (such as Ar-H2), whereas the BFCCCC method Is better for strong-coupling complexes (such as Ar-HCl). These methods have been applied successfully to a number of vdW molecules, using reliable potential surfaces determined by experiments. In particular, the predicted widths for Ar-HD are In good agreement with the recent experimental data of McKellar. 

Furthermore, the requirement that the strong coupling complex be able to dissociate over the final state orbital angular momentum barrier restricts by... 

The observation of the variation of the SCH bands of thiazole with the nature and the position of the substituent has been interpreted as a proof of a fairly strong coupling between the various CH vibrators (203). The couplings are confirmed by the force-field calculation for thiazole that shows that the nature of the 1300-1000 band is rather complex. 

The contrast in knowledge is a result of the degree of complexity of materials properties elastic piezoelectric solids have perhaps the least complex behaviors, whereas ferroelectric solids have perhaps the most complex mechanical and electrical behaviors of any solid under shock compression. This complexity is further compounded by the strong coupling between electrical and mechanical states. Unfortunately, much of the work studying ferroelectrics appears to have underestimated the difficulty, and it has not been possible to carry out careful, long range, systematic efforts required to develop an improved picture. 

Models for emulsion polymerization reactors vary greatly in their complexity. The level of sophistication needed depends upon the intended use of the model. One could distinguish between two levels of complexity. The first type of model simply involves reactor material and energy balances, and is used to predict the temperature, pressure and monomer concentrations in the reactor. Second level models cannot only predict the above quantities but also polymer properties such as particle size, molecular weight distribution (MWD) and branching frequency. In latex reactor systems, the level one balances are strongly coupled with the particle population balances, thereby making approximate level one models of limited value (1).
