我们已经证明，极性分子围绕内电极的充电圆柱形电容器的螺旋轨迹，从一个平移运动的叠加沿着和围绕圆柱轴的轨道运动的结果。用这种方法，分子束可以被引导到任何给定的距离。结果已获得的喷嘴束的NaCl，NaBr，和NaI接种在氪。弯曲成环形的电容器可以用作极性分子在高场寻找旋转态的存储环。
We have demonstrated experimentally that polar molecules revolve around the inner electrode of a charged cylindrical capacitor in helical trajectories that result from a superposition of a translational motion along and an orbital motion around the cylinder axis. In this way molecular beams can be guided over any given distance. The results have been obtained for nozzle beams of NaCl, NaBr, and NaI seeded in Kr. The capacitor bent into a toroid may be used as a storage ring for polar molecules in high field seeking rotational states.
