The consistency of observations, 1 H NMR spectrum of N,N -dimethylformamide, at room temperature and higher temperatures, is to be explained on the basis of the existence of a relatively large barrier to rotation about the carbon–nitrogen bond of DMF. Concept introduction: It is a well-known phenomenon that the variation in the 1 H NMR chemical shifts with varying temperatures. At higher temperatures, the thermal fluctuations result in higher mobility of the atoms, subsequently decreasing the chemical-shift values of amide protons.
