RESUMO
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.
