Özet
H-1 and F-19 MAS, C-13 and N-15 CP/MAS NMR and liquid phase NMR spectra of 4,4'-diaminooctafluorobiphenyl (DAOFB) have been reported for the first time. H-1, C-13 and N-15 NMR chemical shifts of DAOFB (C12H4F8N2) have been Calculated by means of the Hartree-Fock (HF) and Becke-3-Lee-Yang-Parr (B3LYP) density functional methods with 6-311++G(d,p) basis set. Comparison between the experimental and the theoretical results indicates that density functional B3LYP method is superior to the scaled HF approach for predicting NMR properties.
