NMR spectroscopy applied to amine–CO₂–H₂O systems relevant for post-combustion CO₂ capture: A review

Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful non-invasive analytical technique for chemical analyses since direct measurements at a molecular level can be performed. In this work, a survey of NMR spectroscopy applied for studies of CO₂ absorption in aqueous amine solvents (amine–CO₂–H₂O) relevant for post-combustion CO₂ capture is presented. Technical aspects of NMR experiments and the main applications with corresponding results are provided. The overview of the NMR literature in this field suggests that studies of amine–CO₂–H₂O systems can benefit from a further consideration of this spectroscopic technique.
