Abstract The association of anionic surfactants,viz., sodium alkyl sulfates, C n H2n+1OSO3Na (n=5, 6, 7, 8, 9, 10, 12), withβ-cyclodextrin has been investigated by means of NMR spectroscopy. The measurements of chemical shift changes of certain protons of both host and guest molecules indicated 1:1 inclusion complex formation. The association constants (K a) and standard free energy changes (−ΔG 0) for the inclusion complexation reaction vary as a function of the hydrocarbon chain length of the surfactants.
