Spectroscopic Characterization of Solvent-Mediated Folding in Dicarboxylate Dianions

The relationship between conformational changes of suberate dianions in water clusters and the corresponding spectroscopic characteristics were studied theoretically and by IR spectroscopy (see picture for the charge displacement associated with the excitation of the carboxylate symmetric stretching modes). Folded structures are stabilized by the formation of additional hydrogen bonds between the solvated dianion and H2O molecules and should thus be retained in larger, microhydrated clusters.
