Résumé : The second virial coefficient of normal methane, 12CH4, has been compared with that of the corresponding deutero compound 12CD4, as well as with the other isotopic molecule, 13CH4. These measurements were performed by means of a differential apparatus over a range of temperature extending from 110° k up to 300° k . © 1962 Taylor & Francis Group, LLC.
