Abstract

The Cover Feature shows the doubly hydrogen bonded anionic dimers formed in amino acid ionic liquids. Spectroscopic evidence in the far infrared is provided for the tête-à-tête between two glycinate anions despite the repulsive Coulomb forces between the ions of like charge. The torsional motion of the amine groups is characteristic either for the cation–anion or the anion–anion interaction, indicated by specific spectral signatures. Find out more in the Research Article by D. Kotwica and R. Ludwig (DOI: 10.1002/cphc.202500297).

封面专题：用远红外光谱探测氨基酸离子液体中阴离子-阴离子相互作用的证据（chemphychem 19/2025）

覆盖特征显示了氨基酸离子液体中形成的双氢键阴离子二聚体。在远红外光谱的证据，提供了tête-à-tête之间的两个甘氨酸阴离子之间，尽管类似电荷的离子之间的排斥库仑力。胺基的扭转运动是阳离子-阴离子或阴离子-阴离子相互作用的特征，由特定的光谱特征表示。在D. Kotwica和R. Ludwig的研究文章中可以找到更多信息（DOI: 10.1002/cphc.202500297）。

期刊介绍： ChemPhysChem is one of the leading chemistry/physics interdisciplinary journals (ISI Impact Factor 2018: 3.077) for physical chemistry and chemical physics. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies. ChemPhysChem is an international source for important primary and critical secondary information across the whole field of physical chemistry and chemical physics. It integrates this wide and flourishing field ranging from Solid State and Soft-Matter Research, Electro- and Photochemistry, Femtochemistry and Nanotechnology, Complex Systems, Single-Molecule Research, Clusters and Colloids, Catalysis and Surface Science, Biophysics and Physical Biochemistry, Atmospheric and Environmental Chemistry, and many more topics. ChemPhysChem is peer-reviewed.
