Molecular motion and phase transition in hydroquinone clathrate compounds

Invited Contributions


Distinction between the host-guest and guest-guest interaction in the roles they play in determining the physical properties of the clathrate compounds is discussed. It is shown that the latter causes cooperative effects and phase transitions. Experimental data on the phase transitions and molecular motion in the hydroquinone clathrate compounds are reviewed. Dipole interaction between the guest molecules is shown to have a correct magnitude of energy to explain the experimentally found transition temperatures. Possibility of quantum effects in the clathrate property is discussed in relation to the free rotation and ortho-para conversion of the hydrogen sulphide and other guest molecules.
