FTIR spectra of neat acetone (ACT), neat acetonitrile (AN) and their binary solutions at various molarratios 1:2, 1:3, 2:1 and 3:1 (AN:ACT) have been recorded in 4000-400 cm-1 region at room temperature.The acetone is a self-associated molecule and existed as a mixture of monomers, dimers and trimers.The acetonitrile is also a mixture of monomer and weakly bonded dimers. The acetone is associatedthrough the H-bond interaction (ACT)C-H...O=C(ACT) and the acetone and acetonitrile moleculesare interacted through the non-classical H-bonds (ACT) C-H···N≡C (AN) and (AN) C-H···O=C (ACT).
