Abstract
Force parameters for the Buckingham‐Corner (exp 6–8) potential have been calculated for Kr, Xe, and C2H4. For Kr and Xe, crystal data and second virial data have been used. Crystal data could not be used for C2H4. For these substances the exp 6–8 potential has been compared with the other potential forms. It has been observed that the second virial coefficient is not sensitive enough to show the relative importance of the contributions of the r—6 and r—8 terms to the London attractive potential.Keywords
