Abstract

77Se was measured by inverse proton detection using multiple‐quantum 1H‐{77Se} correlation spectroscopy. One‐and two‐dimensional heteronuclear multiple quantum coherence (HMQC) experiments are reported for selenophene, benzeneselenol, dimethyl selenide, dimethyl diselenide, and D,L‐selenomethionine with a range of 77Se1H coupling constants from 9.5 to 54.2 Hz. In these compounds having protons with different 77Se1H coupling constants the different correlations can be selectively enhanced by varying the mixing time. The enhancement for indirect versus direct 77Se detection was estimated for dimethyl selenide yielding a value close to the theoretical enhancement.
