Fig. 1: Schematic illustration of the combined experimental approach to study ion-specific effects on 2Ala.

From: Ion-specific binding of cations to the carboxylate and of anions to the amide of alanylalanine

Fig. 1

Dielectric relaxation spectroscopy probes the dynamics of 2Ala’s electrical dipole (gray arrow), 1H-NMR spectroscopy the chemical environment of 2Ala’s protons (marked green), and 2D-IR detects the vibrational dynamics of the CO and anti-symmetric COO− stretching vibrations of 2Ala (marked brown).
