Dataset from the analysis of dielectric study for liquid crystal dimers based on thioether cyanobiphenyl (CBS5SCB, CBS7SCB and CBS5OCB, CBS7OCB) that form nematic twist-bend phase.

This dataset contains raw data from the analyses published in the article entitled „Dielectric Study of Liquid Crystal Dimers: Probing the Orientational Order and Molecular Interactions in Nematic and Twist-Bend Nematic Phases” in Journal of Physical Chemistry B 2023, 127, 7082−7090. https://doi.org/10.1021/acs.jpcb.3c03496 The data include the raw dielectric spectra for symmetric (CBS5SCB, CBS7SCB) and asymmetric (CBS5OCB, CBS7OCB) dimers as a function of temperature and frequencies of the measuring field (frequencies from 10 to 2× 10 9 Hz). The files from dielectric measurements are in a file with the extension data. The individual file denotes the measurement at a particular temperature, the first column contains the frequencies, the second the real permittivity, and the third the imaginary permittivity. Temperatures in kelvins are given in the header of the first column.

本数据集收录了发表于《物理化学杂志B辑（Journal of Physical Chemistry B）》2023年第127卷第7082−7090页、标题为《液晶二聚体的介电研究：探究向列相与扭转弯曲向列相中的取向序与分子相互作用》的论文中所公开的分析原始数据，原文DOI链接为https://doi.org/10.1021/acs.jpcb.3c03496。本次数据集涵盖对称型二聚体（CBS5SCB、CBS7SCB）与非对称型二聚体（CBS5OCB、CBS7OCB）的原始介电谱（dielectric spectra）数据，这些数据随测试温度与测量电场频率变化，频率范围为10 Hz至2×10^9 Hz。介电测量所得文件的扩展名为.data，每个独立文件对应某一特定温度下的测量结果；文件第一列为频率数据，第二列为复介电常数实部（real permittivity），第三列为复介电常数虚部（imaginary permittivity）；第一列的表头标注了以开尔文（kelvins）为单位的测试温度。
