We studied the reorientational and vibrational dynamics of ethylene glycol and its homologous systems, namely ethylene glycol monomethyl ether and ethylene glycol dimethyl ether, having a different number of OH groups per molecule. The above systems were studied in bulk and in confined state within a porous glass matrix with 25 Å diameter pores by light scattering (Raman and Rayleigh). By comparing the obtained results the evident influence of the chemical and physical traps on the molecular mobility of the liquids forced to diffuse within the nanopores was shown. © 2000 American Institute of Physics.
