The dynamical transition of myoglobin for low hydrations studied with terahertz time domain spectroscopy
Thesis Abstract: 
Terahertz time domain spectroscopy was performed to determine the temperature dependence of metmyoglobin in the range of 80-265K for different hydrations. Metmyoglobin in solution and ground powder was used. A procedure was developed to determine and guarantee hydration levels of the powder samples. The dynamical transition could be observed for hydration h = 0.27 g/g and higher in the real part and for h = 0.19 g/g and higher for imaginary part of the dielectric constant. Fits with the Vogel-Tammann-Fulcher equation indicate a distribution of relaxation processes.
