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
使用多量子 1H-125Te} 相关光谱法通过反质子检测测量 125Te。一维和二维异核多量子相干 (HMQC) 实验报告了二甲基碲化物、二甲基二碲化物、苄基碲氰酸酯、三甲基氯化碲、碲甲硫氨酸、碲酚、1,4-硫碲和二(正丁基)碲化物的一系列125Te–1H 耦合常数从 14.6 到 102.5 Hz。对三甲基碲氯化物估计了间接与直接 125Te 检测的增强作用。理论增强为 50.7,实验估计为 46.2。还举例说明了多量子 1H-123Te} 相关光谱。© 1997 约翰威利父子公司。
