Data from: Salt-screened transition toward bulk-Like water dynamics near polymeric zwitterions

This dataset accompanies the article "Salt-Screened Transition toward Bulk-Like Water Dynamics near Polymeric Zwitterions" by Shawn D. Mengel, Audra J. DeStefano, Thomas Webber, Anton Semerdjiev, Songi Han, and Rachel A. Segalman in ACS Macro Letters in 2024. The article demonstrates how the diffusion of water molecules local to zwitterionic surfaces is modulated by salt screening and hydration structure effects. This dataset contains the necessary experimental data to reproduce the main text and supporting figures. High performance liquid chromatographs, mass spectra, electron paramagnetic resonance spectra and correlation times, and Overhauser dynamic nuclear polarization parameters.本数据集配套2024年发表于《ACS Macro Letters》的文章"Salt-Screened Transition toward Bulk-Like Water Dynamics near Polymeric Zwitterions"，作者为Shawn D. Mengel、Audra J. DeStefano、Thomas Webber、Anton Semerdjiev、Songi Han与Rachel A. Segalman。该文章阐明了盐屏蔽效应与水化结构作用如何调控两性离子聚合物表面附近局域水分子的扩散行为。本数据集包含复现论文正文与补充图表所需的全部实验数据，涵盖高效液相色谱数据、质谱谱图、电子顺磁共振谱图及相关弛豫时间，以及奥弗豪泽动态核极化（Overhauser dynamic nuclear polarization）参数。
