Abstract

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.
