结果表明，线性极性分子和可极化分子与共线电场的永久电偶极相互作用和诱导电偶极相互作用的组合导致相应的Stark能面和其他可观测到的量在永久和诱导偶极相互作用参数所跨越的平面上形成独特的拓扑。我们发现，表面相交的轨迹可以解析地跟踪，并且本征态以及它们相交的数目可以用单个整数指数来表征。该指数的值对于特定的相互作用参数比率是独特的，它与先前通过超对称量子力学装置获得的一类斯塔克态的本征性质有密切的关系。
We show that combined permanent and induced electric dipole interactions of linear polar and polarizable molecules with collinear electric fields lead to a sui generis topology of the corresponding Stark energy surfaces and of other observables - such as alignment and orientation cosines - in the plane spanned by the permanent and induced dipole interaction parameters. We find that the loci of the intersections of the surfaces can be traced analytically and that the eigenstates as well as the number of their intersections can be characterized by a single integer index. The value of the index, distinctive for a particular ratio of the interaction parameters, brings out a close kinship with the eigenproperties obtained previously for a class of Stark states via the apparatus of supersymmetric quantum mechanics.
