The gas-phase structures of the species obtained by the reaction of cisplatin and 2′-deoxyadenosine-5′-monophosphate (5′-dAMP) are investigated by infrared multiple photon dissociation (IRMPD) action spectroscopy combined with quantum-chemical calculations. IRMPD kinetic experiments indicate that the most abundant component in the sampled cis-[PtCl(NH3)2(5′-dAMP)]+ ionic population is the isomer platinated at the N3 position of adenine, in spite of it being the less stable one among the potential candidates.
