Abstract
The association of anionic surfactants, viz., sodium alkyl sulfates, C nH2n+1OSO3Na (n = 5, 6, 7, 8, 9, 10, 12), with beta-cyclodextrin has b een investigated by means of NMR spectroscopy. The measurements of che mical shift changes of certain protons of both host and guest molecule s indicated 1 : 1 inclusion complex formation. The association constan ts (K(a)) and standard free energy changes (-DELTAG0) for the inclusio n complexation reaction vary as a function of the hydrocarbon chain le ngth of the surfactants.
