| Abstract: | The relation between the numbers of substitution atoms and δ( 183 WNMR)walues of "polar" W atoms were investigated.The values of chemical shifts of "polar" W atom in α -1,2-[P 2W 16 Ti 2O 62 ] 10- and in α -1,2-[P 2W 16 (TiO) 2O 60 ] 10- were forecasted.The results in α -1,2-[P 2W 16 Ti 2O 62 ] 10- and α -1,2-[P 2W 16 (TiO) 2O 60 ] 10- showed that the δ values of the W adjacent to Ti was -59.3 ym,-66.5 ym;the δ values of the W "symmetry-related" to Ti was -149.3 ym,-162.6 ym;the δ values of the W "non-symmetry-related" to Ti was -125.4 ym,-131.4 ym. |
