Abstract
Tellurium-125 chemical shifts determined by heteronuclear double resonance in a range of organotellurium compounds are found to parallel closely the 77Se chemical shifts in analogous compounds. The tellurium shielding decreases as the electronegativity of substituents increases and this is attributed to dominance by the paramagnetic term. Variations in ΔE do not appear to be important.Keywords
