摘要 采用激光烧蚀/超声膨胀技术制备氢氧化钙CaOH，进行了泵浦/探针微波-光学双共振实验。观察到与 (0,0,0) X 2 Σ + 电子振动态中三个最低纯旋转跃迁相关的频率，分辨率为 B = 10023.0841(7)、D = 0.01154(5)、γ = 34.7593(10)、b F (H) = 2.602(3)、c (H) = 2.053(10)。质子超精细相互作用根据 X 2 Σ + 态的分子轨道描述进行解释。
Abstract A pump/probe microwave-optical double resonance experiment has been performed on calcium monohydroxide, CaOH, using the technique of laser ablation/supersonic expansion for production of the compound. Frequencies associated with the three lowest pure rotational transitions in the (0,0,0) X 2 Σ + vibronic state were observed with a resolution of B = 10023.0841(7), D = 0.01154(5), γ = 34.7593(10), b F (H) = 2.602(3), c (H) = 2.053(10). The proton hyperfine interactions were interpreted in terms of a molecular orbital description for the X 2 Σ + state.
