The chemical shifts were reported in ppm relative to tetramethylsilane (TMS), which was used as an internal reference standard. 1H-NMR data are reported as follows: chemical shift (ppm), (multiplicity, coupling constant (Hz), number of protons, the corresponding proton(s). Infrared (IR) ...

(DMSO-d 6); chemical shifts are expressed as δ values relative to Me4Si as standard; coupling constants (J) are given in hertz; multiplicity in 1H NMR is reported as singlet (s), broad singlet (br s), doublet (d), doublet of doublets (dd), triplet (t), quartet (q), and ...
1H NMR and 13C NMR spectra were collected in CDCl3 on a Bruker Avance 400 spectrometer with TMS as internal standard at room temperature, 31P NMR spectra were recorded at 162 MHz, and chemical shifts (δ) reported relative to external 85% phosphoric acid (δ = 0.0 ppm), the chemical ...
1H NMR spectra of diacids I and II in DMSO-d6. the overlap shifts of C14 and C14 . The chemical shifts of C9–14 were slightly different with those of C9 –14 because of different linkages. The splitting of the 13C signals caused by couplings between carbon and fluo- rine also could...
