a,b: 1H NMR spectra of 20 mM EuDOTAM-2M-2PB cyclen axial protons in the most downfield region at various temperature in the absence (a) and presence (b) of 20 mM glucose, at 400 MHz, pH 7. The increased line broadening at higher temperatures is due to the more rapid intramolecular exchange process discussed in the text.
