well-known “γ effect” offer a clear understanding of a large number of 77Se chemicalshifts. The same intramolecular polarizability concept can be used when examining the chemicalshifts of tellurides and ditellurides. Here, even larger substituent caused chemicalshifts are observed. Solvent effects on 125Te chemicalshifts of dimethyl telluride were also examined in solvents of varying polarizability. As
