Abstract
Temperature- and hydration-dependent terahertz spectra of hen egg white lysozyme were obtained by using terahertz time-domain spectroscopy. Analysis of the complex dielectric spectra indicated hydration-water dynamics at around 2 picoseconds were thermally activated above 230 K upon hydration.
