Dielectric constant of the medium has been utilised to study the micel
le-reverse micelle transition of linear alkylbenzene sulphonate (LAS).
This transition with changing polarity of the medium is likely to enc
ounter a monomeric state at an optimum dielectric constant of the medi
um. Proton NMR spectroscopy has been utilised to study the aggregation
behaviour of various isomers of LAS at very low and very high concent
rations as function of dielectric constant of the medium. It is conclu
ded that LAS remains in monomeric state even at very high concentratio
ns in solvent systems with a dielectric constant around 41.
