Popis: Time-domain terahertz and Fourier-transform infrared spectroscopy techniques are employed for investigating of the low-frequency dynamics of H 2 O@C 60 endofullerene at temperatures 6–300 K. A number of absorption lines associated with rotational transitions of water molecules entrapped inside C 60 cage are observed and assigned. Fitting absorption lines with Lorentzians allowed us to obtain the temperature dependences of the lines’ parameters – frequency position, strength and damping.
