Abstract

A preparation of [2H1]glycine and [2H1]glycyl[2H1]glycine is described. Deuterium nuclear quadrupole relaxation times have been obtained from proton lineshape analysis of the CHD resonances and are used to calculate the correlation times for molecular motions in these compounds for various conditions. The results show that the local dynamic properties of the molecules depend on ionic state and on the presence of internal motions. Different flexibilities are found for the two ends of the diglycine molecule.
