Abstract

125Te was measured by inverse proton detection using multiple-quantum 1H-{125Te} correlation spectroscopy. One- and two-dimensional heteronuclear multiple quantum coherence (HMQC) experiments are reported for dimethyl telluride, dimethyl ditelluride, benzyl tellurocyanate, trimethyltelluronium chloride, telluromethionine, tellurophene, 1,4-thiatellurin and di(n-butyl) telluride having a range of 125Te-1H coupling constants from 14.6 to 102.5 Hz. The enhancement for indirect vs. direct 125Te detection was estimated for trimethyltelluronium chloride. The theoretical enhancement is 50.7 and that estimated experimentally 46.2. Multiple-quantum 1H-{123Te} correlation spectroscopy is also illustrated for one example.
