Abstract
AbstractThe 1H NMR spectrum of [13C]ethane‐1,2‐diol was measured at natural abundance using the 1H13C inverse‐detected HMQC method with magnetic field gradients. A limited solvent and temperature dependence study was undertaken and the vicinal 1H1H coupling constants were related to those in model compounds. It is shown that the trans rotamer is significantly populated, in contradiction to some recent theoretical and experimental studies.
