Figure 3.

Figure 3

HOM2DJ spectrum and 1H–19F couplings. The 1H NMR is shown in the X axis and the 1H–1H coupling constants are shown in the Y axis. The doublet of doublets resulting from 1H–1H scalar coupling constants are resolved in the Y axis. Two coupling constants (2 Hz, 8 Hz) out of three shown in the Figure for the doublet of doublets of doublets are resolved in the Y axis. The one remaining coupling constant (18 Hz) is resolved only in the X-axis and, hence, corresponds to a 1H–19F coupling.
