A structural investigation of liquid acetamide was performed at 346 K using x-ray scattering. The data are analyzed to yield the molecular structure factor and the distinct pair correlation function. Two H-bonds per molecule are found on average. The mean N⋯O distance is about 3.03 Å. The liquid structure can be described by some structural units similar to the ones existing either in the rhombohedral or in the orthorhombic crystalline form.
