概要	tVibrational modes of a tetrahydrofuran (THF) in a clathrate hydrate (CH) are studied by Raman spec-troscopy. Especially, we focused on around 900 cm-1, where a CCCC stretching mode of THF is mainlyobserved. An asymmetric peak around 900 cm-1, which shows a major CCCC stretching mode of THFwith a minor tailing above 150 K, is observed as clear four modes below 40 K. We concluded that thepeak-splitting is attributed to a restriction of vibrational motions of the guest molecule by the CH-cagewall at low temperature due to a deformation of a force field of the CH-cage for the guest molecule.
