✦ Synopsis


The colour centres S 3 in ultramarine blue have been studied by EPR. Measurements of the temperature dependence of the linewidth have shown that the linewidth can be approximated by the formula: B pp D a C bT 7 , which according to the Kronig's theory is describing the two-phonon Raman process of the transfer of energy to the vibrations of the lattice.

The scaling predictions for the temperature dependence of the intrinsic viscosity of flexible polymers are briefly reviewed. When the predictions are fit to a power law over a fixed range of chain length, a relation between the exponent and prefactor of the Mark-Houwink-Sakurada equation emerges. In
