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.
