Atomic scale electric field fluctuations in liquid tellurium alloys are detected as they induce nuclear spin relaxation rate RQ in noble gas impurity atoms, via quadrupolar interaction. Results for Xe in liquid Ag, Ga, In, Tl, Ge, Sn---Te alloys are discussed, assuming that bonding in these alloys may be described as a mixture of metallic, covalent and ionic bonding. Using an inhomogeneous model, and obtaining the metallic fraction from electrical conductivity, the Xe R0 data are used to derive estimates of the ionic bonding fraction in the alloys studied.
