Abstract
Anisotropic rotation of C6F6 in neat liquid is investigated by the analysis of the ν1 and ν15 (both C-F stretching) bands of Raman spectrum and diffusion constants for the spinning (D∥) and tumbling (D⊥) motions are obtained by the rotational dffusion theory. The same analysis is also carried out for the ν2 and ν16 (both C-C stretching) bands and both results are compared with the results obtained for benzene in neat liquid. The results show that the reorientation of C6F6 is highly anisotropic and the anisotropy is greater for C6F6 than benzene. This is due to the fact that the spinning rate is about the same but the tumbling rate is sharply reduced for C6F6.
