X-RAY-SCATTERING STUDY OF AMORPHOUS FORMAMIDE

Noncrystalline solid formamide can be prepared by vapor deposition ont o substrates kept at 77 K. A structural investigation of the so-obtain ed samples using x-ray scattering indicates that there are, on average , four hydrogen-bonds per molecule. The amorphous structure can be des cribed by a short-range order which resembles the one in the crystalli ne solid. (C) 1998 American Institute of Physics.
