Bond lengths, quadrupole coupling constants, chemical shifts and vibrational frequencies are important probes of hydrogen bonding. This was previously demonstrated for liquid N-methylacetamide (NMA) showing that cooperativity and non-additive contributions of hydrogen bonds play a significant role.
Since the discovery of the multi-drug resistance (MDR) phenotype, reversant agents of various origins and structures have been extensively studied. In the present work, two series of related 2,4,6-tris(amino)-striazines with di †erent MDR potential1 were studied by 15N NMR spectroscopy. The 15N nucl
