Conclusions
-
1.
Correlation times τ of rotational motion of liquid phenol have been measured over a broad temperature range, as well as the correlation times of certain organic compounds dissolved in phenol.
-
2.
The non-Arrhenius temperature dependences of τ, together with the temperaturerelated changes in anisotropy of rotation of the “guest” molecules, indicate strong association of phenol molecules.
-
3.
By means of a modification of the theory of Steele and Huntress, the temperature dependence of τ has been calculated for phenol monomers, and it has been shown that void spaces may be formed in the phenol structure, with most probable dimensions 5–10 Å.
