Brillouin scattering evidence of nonideal mixing in Methanol/CCI4 mixtures
Article Abstract:
A Brillouin scattering experiment is performed on the methanol/CCl4 mixtures as a function of the concentration to test the hypothesis, recently suggested by Raman spectroscopy. It is observed that the results interpreted as due to polarization effects induced by methanol on the isotropic CCl4 molecule that induces some coordination with carbon tetrachloride.

Evidence of heterogeneous aggregation in methanol/CCl4 mixtures: A Brillouin scattering investigation
Article Abstract:
By means of Brillouin scattering experiment in methanol/CCl4 mixtures, deviations of the hypercoustic parameters from the ideal behavior are studied as a function of concentration and temperature. The Brillouin scattering results confirm the idea that, CCl4 is far from behaving as an inert solvent for methanol.

Structural relaxation processes in polyethylene glycol/CCl4 solutions by Brillouin scattering
Article Abstract:
A Brillouin scattering experiment on solutions of poly(ethylene glycol) of mean molecular mass 600 g/mol in CCl4 was described. The relaxation process detected was assigned to conformational rearrangements of the polymeric chains, triggered by reorientation of the side groups.
