摘要

The isotope fractionation of all ozone isotopologs of mass 48-54 #mu# has been measured withhigh accuracy. The data represent a standard for the magnitude of the ozone isotope effect since pressure, temperature, and composition of the gas inwhich ozone is produced are well known. While ~(17)O ~(17)O ~(17)O and ~(18)O~(18)O~(18)O are depleted by -1.5% and -3.9%,respectively, all others are eneriched with ~(16)O~(17)O~(18) showing the highest value of 19.8%. Enrichments or depletions are independent of the isotope composition of the oxygen gas.
