The time resolved optical Kerr effect (OKE) has been applied to aqueous urea (w urea ¼ 0.18) at different temperatures ranging from 283 to 333 K in order to investigate the behaviour of the different reorientational relaxation times and the low frequency OKE response of the system. The relaxation times follow the Debye-Stokes-Einstein (DSE) theory. These results reveal that at a microscopic level the reorientation of a molecule of urea is anisotropic. This anisotropy is expressed as andoi:10.1039/b305654f fatcat:qymymrhuubcbhjle4oxur66vo4
