N2 - The Tolman length (δ∞) characterizes the first-order correction to the surface tension (σ∞) due to curvature of the interface. Statistical mechanical expressions for σ∞ and δ∞ were derived previously by Blokhuis and Bedeaux [Physica A 1992, 184, 42] for nonpolar fluids. Here Blokhuis and Bedeaux's approach is extended to dipolar fluids. Two approximations to the pair correlation function are employed, and their effects on σ∞ and δ∞ are examined. The dependence of σ∞ and δ∞ on temperature and dipole moment is also explored. It is found that σ∞ increases with the dipole moment while |δ∞| decreases as the dipole moment is increased. The sign of δ∞ is, however, negative.
