On the selection of the intermolecular potential function :

On the utility of the m-6-8 potential function

“…Solutions of eq (13) for argon at several experimental temperatures as in figure 3. Note the very small area given by the 11-6-8 with Y = 3.0 29 5. Continuation of figure 4.…”

“…The point at each temperature corresponds to the b^and e/k values which give a simultaneous fit of the viscosity coefficient and second virial coefficient at that temperature 27 3.…”

“…We introduce the more convenient reduced form of potential (3) as follows. (^f (5) m \ r y -z(^r + (-8)(-Lf (6) with r' -r/r .…”
