异常大的线性和二次塞曼位移测量弱结合超冷88 Sr 2分子附近的相互结合线渐近线。非绝热科里奥利耦合和长程分子势的性质解释了这种效应是如何产生的，并与分子的大小大致成立方关系。线性位移产生分子态的非绝热混合角。的二次移位是敏感的附近相反的f-宇称状态，并表现出四阶校正，提供了一个国家的最先进的从头算模型的严格测试。
Anomalously large linear and quadratic Zeeman shifts are measured for weakly bound ultracold 88Sr2 molecules near the intercombination-line asymptote. Nonadiabatic Coriolis coupling and the nature of long-range molecular potentials explain how this effect arises and scales roughly cubically with the size of the molecule. The linear shifts yield nonadiabatic mixing angles of the molecular states. The quadratic shifts are sensitive to nearby opposite f-parity states and exhibit fourth-order corrections, providing a stringent test of a state-of-the-art ab initio model.
