摘要：

The measurement of the rotational relaxation time of seven fluorene derivatives in dimethyl sulfoxide and paraffin oil is used to assess the generality of a recently proposed model of dielectric friction. This work shows that the friction experienced by these solute molecules is reproduced quite well at a qualitative level. Although agreement between the experiment and the model can also be captured by adjusting certain parameters, these adjustments are not always clearly correlated with molecular properties.
