H-bonding in liquid N-methylformamide as studied by X-ray scattering

A structural investigation of liquid N-methylformamide, C2H5NO, was performed at room temperature and atmospheric pressure using X-ray scattering. Experimental data are analysed to yield the molecular structure factor and the distinct pair correlation function. The more dominant form (cis or trans) is considered and the H-bonding parameters are deduced. In order to describe the local arrangement in the liquid, different models are examined.
