• The phase-twisted lines, resulting from a double complex Fourier transform, can greatly alter the quality of two-dimensional spectra. This problem, which is generally overcome by experimental procedures (requiring twice as much time as a standard measurement), is inevitable in the two-dimensional J-resolved experiment. This experiment is revisited theoretically and a postprocessing treatment, leading to pure 2D J-spectra, is deduced. Quantitative fully J-decoupled homonuclear spectra are accordingly obtained by means of a projection onto the F2 axis after a 45° tilt.
