利用激光分子束光谱技术研究了线性氰化氢三聚体的强束缚摆动态。频谱经历了一个戏剧性的演变，从一个自由转子的零电场，其特征P和R分支结构，到一个大电场约束的钟摆（对应于ω = μ-E/B = 365）的指示。结果是线性分子的取向程度前所未有。使用弱结合配合物的一般性取向，甚至非极性分子进行了讨论。
Infrared-laser-molecular-beam spectroscopy has been used to observe strongly bound pendular states of the linear hydrogen cyanide trimer. The spectrum undergoes a dramatic evolution from that of a free rotor al zero electric field, with its characteristic P and R branch structure, to that indicative of a pendulum bound by a large electric field (corresponding to omega = mu-E/B = 365). The result is an unprecedented degree of orientation for a linear molecule. The generality of using weakly bound complexes to orient even nonpolar molecules is discussed.
