Abstract

|
|
|
The reorientational motion of C6F6 in neat liquid is investigated in the temperature range 293∼333K by analyzing ν2 and ν16 bands of its Raman spectrum. Diffusion constants for the tumbling (D⊥) and spinning (D∥) motions are determined. The reorientation of the molecule seems to be distinctly anisotropic. Based on the hydrodynamic model, the tumbling motion of the figure axis of C6F6 is largely diffusional. On the other hand, the spinning motion of the same axis looks mostly inertial.
