N2 - The absolute viscosity of highly enriched heavy-oxygen water, H 218O, has been measured at 5°C intervals between 15 and 35°C, using a semi-automatic closed viscometer of the suspended-level type. A linear extrapolation was performed to determine the viscosity of 100% heavy-oxygen water, based upon the measured viscosity of natural water and that of a highly enriched heavy-oxygen water sample. The effect of isotope substitution on the viscosity of natural water has been analyzed for both H 218O and D216O. The viscosity ratio at 25°C for H218O/H216O is 1.0536, whereas that for D216O/H216O is 1.2316.
