A carbon-13 nuclear magnetic resonance study of compounds substituted by a perfluoroalkyl chain

The ¹³C NMR spectra of alkanes, alkanones and cyclohexanones substituted by perfluoroalkyl groups, R_F, have been studied. The influence of the perfluoroalkyl group on the chemical shifts of other carbons of the molecules is the same regardless of the R_F chain length.
