No evidence for proton transfer along the N-H...O hydrogen bond in N-methylacetamide: neutron single crystal structure at 250 and 276 K
Article Abstract:
Single-crystal neutron diffraction method is used to investigate the crystal structure of N-methylacetamide at two temperature, 250 and 276 K. Result reported no evidence for proton transfer along the N-H...O hydrogen bond at either temperatures, but a short intramolecular contacts between the amide hydrogen atom and those on both neighboring methyls is found, which may affect the vibrational properties of the respective molecular groups.

Dynamics of crystalline N-methylacetamide: temperature dependence of infrared and inelastic neutron scattering spectra
Article Abstract:
A study was conducted to analyze the properties of crystalline N-methylacetamide (NMA). The spectra of the isotopic derivatives of NMA were obtained at six temperatures in the range 20-150 K using a filter difference spectrometer. Experimental results indicated that the temperature dependence of the intensities of the librations of the methyl groups in NMA supported no indication for a possible methyl-methyl coupling.

Infrared and inelastic neutron scattering study of the 1.03- and 0.95-nm kaolinite- hydrazine intercalation complexes
Article Abstract:
The interaction of hydrazine with kaoline was studied using a combination of infrared (IR) spectroscopy, inelastic neutron scattering (INS), and X-ray powder diffraction. The combined application of crystallographic methods has provided new insights into the structure and bonding of the KH intercalation complex.
