The complete assignment of F-19, H-1 and C-13 NMR spectra of 11 trifluoromethylated and four bistrifluoromethylated monomers for bridge trifluoromethylated poly(p-phenylenevinylene) is described. The combination of one-dimensional F-19, H-1 and C-13 spectra, long-range fluorine couplings and the two-dimensional techniques of direct and long-range HETCOR (J = 140 and 8 Hz) permitted full resonance assignment.
