Nuclear Quadrupole Interactions atTe125in the Isoelectronic Crystalline Hosts of S, Se, and Te

Abstract
A systematic increase in Te125 quadrupole splitting of up to 54% has been observed in the isoelectronic crystalline hosts of Te, Se, and S. This is attributed to nonlocal and overlap electronic contributions to the electric field gradient qe1, which increase as a result of a systematic shortening of the covalent bonds.
