Dynamical disorder and reorientation of the CH3 groups in N-methylacetamide

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

By selective deuteration the influence of the environment on the geometry of the motion of each hydrogen group in N-methylacetamide (NMA, CH 3NHCOCH3) was probed using quasi-elastic neutron scattering. From 100 K to ambient very good agreement was obtained over the entire Q-range (0.35-2.35Å), by fitting the data to a uniaxial rotational model of the methyl groups around the C3-axis.
