1H and 13C NMR studies of glycine in anisotropic media: Double-quantum transitions and the effects of chiral interactions

► Glycine shows under anisotropic conditions a dipolar doublet in its 1H NMR spectrum. ► Suppression of the doublet occurred most when irradiated in between the two signals. ► This phenomenon is due to double-quantum transitions. ► Extra signals in 1H and 13C NMR were found for glycine-2-13C in chiral anisotropic gels. ► Modelling suggested a 2JHH of −16.5 Hz and two distinct DC,H for the -13CH2- group.
