Temperature, induced structural changes

Unlike aqueous solutions, a typical Arrhenius dependence for the reverse systems is maintained only before a certain critical temperature (T ), while above this temperature a decrease in occurs with tanperature. The value of is found to coincide with the percolation threshold temperature. We assume that the same temperature induced structural changes of the reverse micelles are responsible for the clnstering of the reverse...

From the method development and robustness point of view, the temperature is a parameter that controls equilibria such as pK and enantiomer—chiral selector complexation, or induces structural changes in, e.g., proteins.For chiral separations, generally a lower temperature results in better enantioseparation, but even the opposite has been observed. Sometimes a raise in temperature does not so much affect the enantiomeric separation, but increases the resolution between an enantiomer and a matrix component. ... 

In most cases when the temperature of measurement is above the glass transition, the effect of temperature leads to very complicated spectral effects since structural changes and temperature-induced spectroscopic changes are occuring simultaneously 201,322) jn some the structural changes are well defined as in the case of polystyrene 322).
