The present work cites the measurement results for fluorine NMR chemical shifts in several d10-element fluorides previously not investigated. At the same time, the fluorine chemical shift values in alkali, alkali-earth and some other metal fluorides were measured anew. (This was necessitated by ...

The database has over 500 compounds and 3000 chemical shifts. We can ask questions both about compounds as a whole or individual flourines. Some structures in the literature are inconsistent with the reported nmr parameters. Chemical shift assignments which were not possible earlier can now be ...
Characteristic chemical shifts of each salts' NMR spectra are reported in the methods chapter. The Raman spec- trum of NaPCPI shows multiple nitrile ν(CN) stretching bands near 2250–2180 cm−1; resulting from its linear structure31. The strong band at electron is shared between the ...
Seven complexes of general formula TiF4·CH3C(O)N(CH3)2,4-ZC 5H4NO, where Z represents a para-substituent, were studied by F19 nmr. The chemical shifts were correlated with appropriate Hammett substituent constants.DOI: 10.1021/ic50047a003 被引量: 56 ...
