Excess molar volumes (VmE) were calculated from density values and correlated with Redlich-Kister polynomial equation. Partial molar volumes at infinite dilutions (Vm,i{\^a}??) of the ILs and methanol were determined from the Redlich-Kister coefficients. For all the studied systems, the VmE is negative over the entire composition range. The VmE and Vm,i{\^a}?? are interpreted in terms of intermolecular interactions in the binary mixture. Density functional theory has been used to investigate the interactions between methanol and the studied ILs. {\^A}{\copyright} 2015 Elsevier B.V.}, author = {Gonfa, G. and Bustam, M.
