Abstract
The p, T-dependence of the self diffusion coefficients D for ethanol-O D, 1 - and 2-propanol-OH and -OD have been studied in a wide temperatu re range at pressures up to 200 MPa. The experiments were performed in strengthened high pressure glass cells by the pulsed field gradient N MR-technique. The isobaric temperature dependence of D is given by the VTF-equation. The isotherms can be fitted to the rough hard sphere mo del with an A-parameter that decreases strongly with falling temperatu re.
