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.

建立了全新的线型分子2CLJDQP势能模型，考虑了偶极作用、四极作用及诱导作用的影响，还考虑了极轴与分子轴不平行的情况；回归了多种线型分子的势能参数；通过改进混合规则，可应用同核线型分子的势能参数直接计算异核线型分子的第二维里系数；扩展该模型可用于线型三原子分子计算；讨论了各长程引力项对第二维里系数的贡献，结果表明本模型引入诱导作用等是十分必要的。
