Abstract
Three methods of effective molecular size evaluation originated from scaled particle theory (SPT) and a method proposed by Dejardin et al are checked by correlation analysis on internal consistency. It was shown that the Dejardin's method looks more attractive than SPT methods for estimation of the molecular radii r. Temperature dependence of r is analyzed from the viewpoint of SPT and compared with data of spectral shift experiments. Temperature shifts of S1 S2 spectrum of anthracene dissolved in different solvents are as example of such analysis. In accordance with SPT prediction the estimated values of r decrease with temperature increase only in approximation of neglecting of its out-of-plane core vibrations of anthracene.
