Abstract
An attempt has been made to study the librational excitations in the partially ordered phase II of solid C. The only parameter of the theory is fully determined by static properties of the system. The time-dependent Hartree approximation has been used to calculate the frequencies of the excitations. It is shown that the ordinary harmonic theory is not a good approximation for the system under study.
