The 1H n.m.r. spectra of NN-dimethyltrifluoroacetamide which have been recorded in various solvents, exhibit two H-F coupling constants which are believed to arise from different coupling mechanisms. The high-temperature rotationally averaged spectrum shows that the two H-F coupling constants have the same sign. The activation parameters for the hindered internal rotation about the central C-N bond have been redetermined by line-shape analysis of the temperature-dependent high-resolution 1H n.m.r. spectra.
