X-ray scattering study of amorphous formamide.
Résumé
Noncrystalline solid formamide can be prepared by vapor deposition onto substrates kept at 77 K. A structural investigation of the so-obtained samples using x-ray scattering indicates that there are, on average, four hydrogen-bonds per molecule. The amorphous structure can be described by a short-range order which resembles the one in the crystalline solid.
