A. Pyka, TOPOLOGICAL INDEXES AND R(M) VALUES FOR PREDICTION OF THE DIPOLE-MOMENTS OF SELECTED ISOMERS .12., JPC. Journal of planar chromatography, modern TLC, 9(3), 1996, pp. 181-184
Isomeric disubstituted benzene derivatives have been separated by TLC
on silica gel. For prediction of the values of the dipole moments (mu)
) of the selected isomers investigated the best correlation was obtain
ed with triparametric equations which combined R(M) values with the to
pological indexes B-0 and B-1 or with B-0 and B-2. This is the first t
ime topological indexes have been used for prediction of dipole moment
s and constitutes a new application of thin-layer chromatography. The
investigations were semi-quantitative in nature.
