Relaxation times τ2 and τ1 for inter molecular rotation and intra molecular rotation of binary (jk) polar solution of two amide(j) and phenol(k) in C6H6 at 35°C are derived from susceptibility measurement method in terms of complex high frequency susceptibility (χijk*) under high frequency electric field(9.37 GHz). All the eight systems shows two relaxation time τ2 & τ1 and dipole moments µ2 & µ1 using single frequency concentration variation method. In complex ternary systems of polar non-polar liquid mixture, τ value increases with acidity of amide (proton donor). The calculated relaxation time (τ’s) and dipole moment (µ’s) are excellently matched with the reported values signifying proposed method importance. Solute-solvent and solute-solute molecular associations are predicted in different molecular situations because of different electron affinity of adjacent atoms. Thermodynamic energy parameters are calculated to determine molecular dynamics of the system using Eyring rate theory.
