The self diffusion of the three alcohols with the n-pentane carbon skeleton has been studied as function of temperature and pressure. The temperature was varied from 470 K into the deeply supercooled range. The maximum pressure reached was 200 MPa. In order to study the influence of the isotopic substitution upon the molecular dynamics, the three isotopomers with deuterons in the hydroxyl position were also investigated. Contrary to the situation for ethanol and the two propanols, no dynamic isotope effect is observed when the pairs of the deuterated and the protonated alcohols are compared. The T, p-dependence of the self diffusion is well characterized by the VTF-equation. Application of the rough hard sphere model demands a rotation translation coupling parameter that decreases rapidly with falling temperature.
