Conformation redistribution

Glass transition temperature is a very useful parameter which helps in the verifieation of plasticizing quality of various additives. It is assumed that energetic effects are created by binary heterocontacts which cause conformation redistribution in the neighborhood of these contacts. This assumption results in the following equation ... 

Photorefractivity is a property exhibited by some materials in which the redistribution in space of photogenerated charges will induce a nonuniform electric space-charge field which can, in turn, affect the refractive index of the material. In a new material the active species is a highly efficient cyclopalladated molecule97,98 shown in Figure 5. The palladium-bonded azobenzene molecule is conformationally locked, and gratings derived from cis—trans isomerizations can be safely excluded. 

In the conjugated system C=C—N the configuration on N can be assumed as planar. Then the conformation can be unambiguous and attention is focused on the electron redistribution due to conjugation. For instance, in 18 the conformation was not exactly known conjugation was expressed89 by the mesomeric moment of 0.9-1.5 D, calculated in a rather complex way. 

In addition to the theoretical studies of equilibrium adsorption, Roginskii has conducted extensive investigations of the kinetics of adsorption on nonuniform surfaces and has shown that the character of the kinetics of adsorption is dependent upon the presence or absence of surface migration. Migration of the adsorbate molecules brings about a redistribution which conforms with the values of the adsorption coeffi-...
