The NMR Spectra of CF3I, CF3IF2, and CF3IF4The 19F-NMR and 13C-NMR spectra of CF3I, CF3IF2 and CF3IF4 were recorded in acetonitrile solution. The chemical shifts of the CF3-groups are strongly dependent on the oxidation state of the iodine atom. With increasing oxidation state the resonances of the CF3-groups in the 19F-NMR spectra are characteristically shifted to high field, whereas in the 13C-NMR spectra a characteristic shift to low field is measured. The absolute value of the coupling constants 1J(19F—13C) increases with increasing oxidation state from 344 Hz (CF3I) via 354 Hz (CF3IF2) to 359 Hz (CF3IF4).
