A new theoretical model, the 2CLJDQP potential function, was developed for linear molecules, which takes into account dipole, quadrupole and induction effects as well as the rotation of the dipole out of the molecular axis. The energy parameters were optimized for various types of fluids. With the modified mixing rules, the potential parameters obtained from homonuclear molecules can be used to calculate the second virial coefficients of heteronuclear molecules. The model was also successfully extended to triatomic molecules. Analysis of the contributions to the second virial coefficients of long-range interactions shows that the molecular interactions introduced in the present model, such as, the induction effects, cannot be neglected.

Through the analysis of De, an alternative mechanism interpreting of the"overshoot"phenomena can be obtained: when the diffusing time of small molecular penetrants is shorter than relaxation time of the involved polymer, small molecular substance penetrates into the polymer quickly and its concentration reached a maximum, then the swelling of the polymer by the small molecules makes the chain structure of the polymer relaxed, thus the free volume in polymer matrix, which is occupied by small molecule, decreased, and will squeeze part of the small molecular substance out of the polymer, and therefore overshoot behavior can be observed.
