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.
