Abstract

This study revealed a linear correlation between the nanometer-scale oil droplet sizes estimated using small angle X-ray scatterings (SAXS) and the ¹²⁹Xe NMR chemical shift in an oil-in-water ternary microemulsion system comprising pentaethylene glycol mono-n-dodecyl ether, n-decane, and deuterium oxide. The absolute values of the droplet size estimated using ¹²⁹Xe NMR show good agreement with those using SAXS. We also found that the results are consistent with a reported relation derived using small angle neutron scattering. The results suggest the validity of ¹²⁹Xe NMR chemical shifts for investigation of colloidal systems to evaluate their internal structures' characteristic sizes.
