A theory for non-equilibrium shear relaxation in liquids at low frequencies is presented. It is based on molecular considerations used in theories of low frequency depolarized light scattering. The results for the complex shear impedance contain terms in addition to those obtained by the phenomenol
A mixture of IO\% pressure SF6 snd HCI gas is subjected to P( 16)-COz iaser radiation. The ensuing iiuorescent sigafs from the WCI vibration and ground-stste rota?ions axe spectroscopic&y resolved and their tmnsisnt behaviour is measured. The fluorescent sign& are used to monitor the coliisionally i
From a previous published spectroscopic analysis we know that a solid sample of polyoctyl-(and polyhexyl-) thiophene is a two-phase system characterized by the coexistence of an ordered (0) and of a disordered (D) structure. We show here that by time-temperature studies at low temperature the sample
