• The rotational motion of a rodlike molecule constrained in a potential cage in liquids is studied. This motion is considered in terms of the correlation in function <P_ι[u(0)・u(t)]> of the molecular axis vector u.(P_ι is the l'th Legendre polynomial; l=1 and 2 correspond to the vector and the tensor correlation function respectively.) The correlation functions are shown to be composed of two parts: One is due to rotational diffusion caused by variation of the constraining cage, and the other is due to rotational libration inside the cage. The correlation functions and their spectral densities are calculated for two simple typew of the constraining potential: Suqare-well and harmonic. The integrated absorption intensity of a pure rotational band for polar rodlike molecules is discussed.
