Abstract.

In order to study the dynamics of a phospholipid and its hydration water, we measured complex dielectric spectra of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) from the sub-GHz to the THz frequency region with varying the temperature and hydration level of the sample. Spectra obtained from a vector network analyzer and two terahertz time-domain spectrometers are adjusted, which enables us to analyze the dielectric spectra from the sub-GHz region to the THz region by a model function. We confirmed a fast relaxational mode in the sub-THz region, which was suggested by the previous work which only used a THz spectrometer.

DMPC的水合脂质双层的亚GHz至THz的宽带介电谱。

摘要。

为了研究磷脂及其水合水的动力学，我们测量了随温度变化而从亚GHz到THz频率区域的1,2-二肉豆蔻酰基-锡-甘油-3-磷酸胆碱（DMPC）的复杂介电谱和样品的水合水平。调整了从矢量网络分析仪和两个太赫兹时域光谱仪获得的光谱，这使我们能够通过模型函数分析从亚GHz区域到太赫兹区域的介电谱。我们确认了在亚太赫兹区域内的快速弛豫模式，这是先前仅使用太赫兹光谱仪的工作所建议的。
