Summary, etc. The density (ρ) and refractive indices (n<sub><img src="http://www.niscair.res.in/jinfo/smaller.gif" border="0" alt="" /></sub>) of binary mixtures of formamide (FA) with dimethylethanolamine (DMEA) and diethylethanolamine (DEEA) have been recorded at different temperatures for the whole composition ranges. The experimental values of density data and refractive index are used to estimate the molar refraction (R<sub>m</sub>), reduced molar free volume (V<sub>m</sub>/R<sub>m</sub>), molecular radii (r) and internal pressure (P<sub>int</sub>). The deviations of refractive index (Δn<sub>D</sub>), molar refractions (ΔR<sub>m</sub>), reduced molar free volumes Δ (V<sub>m</sub>/R<sub>m</sub>) and internal pressures (ΔP<sub>int</sub>) have been also calculated. The variations of these parameters with composition and temperature of the mixtures are discussed in terms of molecular interactions due to physical, chemical and structural effects between the unlike molecules. The applicability of different refractive index mixing rules is tested against the experimentally measured values and good agreement has been obtained.
