Abstract :
Absorption coefficients and refractive indices of biologically important macromolecules such as lysozyme and myoglobin and small molecules such as adenosine triphosphate (ATP) have been obtained in the low-frequency region by terahertz time-domain spectroscopy (THz-TDS) to understand molecular dynamics and interactions of these molecules.
