Abstract

The Cover Feature illustrates a very broad ¹⁴N NMR spectrum, typically challenging to acquire due to its low sensitivity and breadth, yet now addressable via the new PROgressive Saturation of the PRoton reservoir Under Spinning (PROSPRUS) NMR experiment. PROSPRUS boosts the signatures of insensitive nuclei possessing broad solid-state NMR spectra under magic-angle spinning, by indirectly detecting their effects via a magnified depolarization of protons throughout the powdered sample. More information can be found in the Research Article by L. Frydman and co-workers (DOI: 10.1002/cphc.202400613).

封面专题：魔角旋转下质子储库的逐渐饱和提高了超边线 NMR 的灵敏度（ChemPhysChem 19/2024）

封面特写展示了一个非常宽的 14N NMR 光谱，由于其灵敏度和广度较低，通常很难获得，但现在可以通过新的旋转下质子库渐进饱和 (PROSPRUS) NMR 实验来解决这个问题。PROSPRUS 通过在整个粉末样品中放大质子去极化，间接检测其影响，从而增强了在魔角旋转下具有宽固态 NMR 光谱的不敏感核的特征。更多信息，请参阅 L. Frydman 及其合作者的研究文章（DOI: 10.1002/cphc.202400613）。

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.
