Structure of Pb2+/dCMP and Pb2+/CMP complexes as characterized by tandem mass spectrometry and IRMPD spectroscopy

Formation of macrochelate forms for Pb2+/deoxycytidine-5′-monophosphate and Pb2+/cytidine-5′-monophosphate complexes is demonstrated by tandem mass spectrometry and mid-infrared multiple-photon dissociation (IRMPD) spectroscopy.
