Abstract: FTIR spectroscopic studies have been carried out on the equimolar binary solution of ethyl acetate with bromobenzene. From the studies it has been found that there are possibilities for hydrogen bond formation between hydrogen in bromobenzene and the oxygen in ethyl acetate. Red and blue shifts have been observed in the asymmetric stretching modes of methyl and methylene group, respectively, of ethyl acetate in the binary solution. This may be due to the dissociation of ethyl acetate and/or the hetero-interactions with bromobenzene. Dielectric relaxation studies have been carried out using time domain reflectometry in the frequency range; 10 MHz to 30 GHz at 298 K on the ethyl acetate- bromobenzene binary solutions over the entire composition range. From the corrective Kirkwood correlation factor values it has been inferred that the hetero-interactions present in the solutions are weak in nature.
