摘要：

Dielectric behavior of some substituted esters compounds, namely, ethylsalicylate, amyl butyrate, methylanthranilate, amyl benzoate, ethypropionate dimetylphthalate, isobutyl benzoate and n-butyl acetate at room temperature are carried out at two frequencies: 9.73 GHz and 7.26 GHz. The results are discussed in terms of a single relaxation Cole and Cole model. In general it has been observed that the tau values observed in the pure liquid phase are longer by an order of 10 compared to their dilute solution values due to increased dipole interactions.
