Triple 13C-{1H, 2H}
NMR – precision quantitative method for study of deuterosabstituded organic
compounds
Abstract
The advantages of quantitative 13C NMR-{1H, 2H} spectroscopy to study the deuterated organic
compounds were shown. The simultaneous use of two saturating fields at protons
and deuterons frequencies leads to a significant simplification of the spectra
and increase sensitivity. Performance capabilities of triple resonance were
demonstrated by an analysis of the isotopomers mixture of tetradecane and
precision measurement of isotope shifts Δ(13C) for biphenyl-d5.
Key words: quantitative 13C NMR-{1H, 2H} spectroscopy, triple NMR, NMR isotopomer analysis,
isotope chemical shifts, deuteroisotopomers, biphenyl-d5.
