摘要：
Interface matters! Photoelectron spectra of aqueous solutions of monoethanolamine (MEA) that had been treated with CO2 were used to determine the spatial distribution of MEA and the reaction products with respect to the solution interface (see picture). Neutral MEA shows a propensity for the solution surface, whereas protonated MEA and the reaction products prefer bulk solvation. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
