Abstract: The ultrasonic velocities (<i style="">U</i>) and densities (r) are measured for solutions of biphenyl, thioanisole and diphenylsulphide and mixtures containing equimolar concentrations of these compounds and 1-chlorobenzotriazole (1-CBT) at 303 K in the concentration range 6<img src='/image/spc_char/cross.gif' border=0>10<sup>-4</sup>-3<img src='/image/spc_char/cross.gif' border=0>10<sup>-3</sup> M. Toluene was used as solvent for the biphenyl-1<b style="">-</b>CBT system and 1,4-dioxane was used as solvent for the other two systems. The coefficient of viscosity (<img src='/image/spc_char/Etta.gif' border=0>) values are determined for the mixtures at 303 K. The acoustical parameters such as adiabatic compressibility (<img src='/image/spc_char/beta.gif' border=0>), free length (<i style="">L</i><sub>f</sub>), relaxation time (<img src='/image/spc_char/tow.gif' border=0>) and free energy of activation (<img src='/image/spc_char/delta.gif' border=0><i style="">G</i><sup>#</sup>)<sup> </sup>values are also calculated. The trend in acoustical parameters indicate that there are molecular interactions between the components and the formation of a charge transfer complex between aromatic compound (donor) and 1-CBT (acceptor) is established.
