H–F Coupling constants and hindered internal rotation in NN-dimethyltrifluoroacetamide
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 t...
