摘要

应用射频功率进行CEST测量需要平衡热效应、灵敏度和光谱分辨率。封面展示了Xe的化学变化，在瓜bbb_uril中快速交换，在加密- a中缓慢交换，如何对温度变化做出不同的反应。快速交换的CEST响应对饱和功率的变化更为敏感。更多信息可以在R. Schoof， L. Schröder及其同事的研究文章中找到（DOI: 10.1002/cphc.202401037）。Barth van Rossum的艺术作品。

Front Cover: RF Heating Effects in CEST NMR with Hyperpolarized 129Xe Considering Different Spin Exchange Kinetics and Saturation Schemes (ChemPhysChem 8/2025)

The application of RF power for CEST measurements requires heating effects, sensitivity, and spectral resolution to be balanced. The Front Cover shows how the chemical shifts for Xe, with fast exchange in cucurbit[6]uril and slow exchange in cryptophane-A, respond differently to temperature changes. The CEST response for fast exchange is much more sensitive to changes in saturation power. More information can be found in the Research Article by R. Schoof, L. Schröder and co-workers (DOI: 10.1002/cphc.202401037). Artwork by Barth van Rossum.
