Abstract: The monoethanolamine (MEA)-water system has been studied by IR spectroscopy and quantum-chemical calculations (DFT B3LYP). It was found that spatial networks both of water and MEA are continuously rearranging depending on the content of the system components. Water molecules are embedded into the net of MEA, and molecules of MEA into the water net, thereby forming a mixed network of hydrogen bonds.

Keywords: IR spectroscopy, spatial hydrogen bond networks, monoethanolamine, water
