At 308 K, using a 9.37 GHz dielectric relaxation setup, dielectric investigations of H-bonded complexes of Propanamide and Butanamide with 4-bromophenol, 4-chlorophenol, 4-iodophenol and 4-fluorophenol in benzene were performed. Various parameters of dielectric like (ε′), (ε″), (ε0) and (ε∞) have been tested. The group rotation relaxation time τ(2) is a function of the steric interactions of the proton donor, while the significance of Higasi et al. single frequency equation used for few relaxation times τ(1) is creates towards a role of the hydrogen bonding power of the phenolic hydrogen. The dielectric relaxation process like the viscous flow process may be defined as a rate process. Higasi's approach yields the maximum relaxation time values at 1:1 molar ratio for the complicated system under consideration. The system under investigation illustrates that the relaxation time value increases as the concentration of solute increases. [ABSTRACT FROM AUTHOR]
