Van der Waals benzene

For molecular species, the interaction is to be interpreted as some kind of average over all the possible geometries. A typical plot for the van der Waals benzene-benzene interaction is shown in Figure 1.12. 

The PMR spectra of the M(R2Dtc)3 complexes (M = As, Sb, Bi) in benzene show solvent shifts induced by the ring current of benzene, which are interpreted in terms of 1 1 van der Waals benzene--M(R2 Dtc) 3 adducts. The association constants for these adducts appear to parallel the polarity of the C-N bond in the R2Dtc ligands (422).
