Self-diffusion coefficients give insight into the mobility of molecular species and serve as benchmark
variables for molecular modeling. Nuclear magnetic resonance (NMR) spectroscopy is an excellent
method for the measurement of self-diffusion coefficients: In the present work, a pulsed gradient
stimulated echo (PGSTE) pulse sequence was employed for their determination in binary and ternary
liquid systems at 298 K and 1 bar. To ensure a high quality of the measurements, a preliminary gradient
mapping was carried out. The experimental results are compared to molecular simulation data by
Guevara-Carrion et al. [1] for binary systems (acetone/toluene, acetone/ethanol and
acetone/cyclohexane) and to molecular simulation data that was determined in the present work for the
ternary system acetone/toluene/cyclohexane.
