Specific acoustical impedance (Z), isentropic compressibility (k,), intermolecular free path length (Lr), cla~sical absorption coel'ficient (a/f2)cl and viscous relaxation time (τ) have been determined from p,ƞ and U data and arc correlated with concentration. Z, (a/f2)el and τ increased with C and decreased with T, while k, and Lr decreased with C and increased with T in the soh·ent systems studied. A fairly good to excellent correlation between u given parameter and concentration is observed at 303, 308 and 313 K and solvent systems studied. Linear incrcase or decrease of acoustical parameters with concentration and temperature indicated existence of strong molecular interactions. EANRA has structure forming tendency.
