Correlation between 77Se and 125Te chemical shifts in related heterocycles
1987
A linear relationship was observed between the 77Se and 125Te chemical shifts in 14 model heterocycles (including 17 new data). The line slope, 1.3, is discussed in terms of Jameson and Gutowski's expression for the Ramsey paramagnetic term, σP. The shifts are also compared with the 17O chemical shifts in related compounds.
