在CF4/He混合物中空心阴极放电，获得了CF+ 4中[Dtilde] 2A1-[Ctilde] 2T2跃迁的高分辨率发射光谱。基于Watson为四面体分子建立的哈密顿量模型，分析了0-0、10 - 1和10 - 2波段的部分分辨旋转结构。通过计算机模拟和枝头之间的间隔关系确定了光谱常数。发现低电子态的自旋轨道耦合、科里奥利相互作用和Jahn-Teller畸变相对较小，但表现出对v1的振动依赖。
High-resolution emission spectra of [Dtilde] 2A1-[Ctilde] 2T2 transitions in CF+ 4 were obtained from a hollow cathode discharge in CF4/He mixtures. The partly resolved rotational structures of the 0-0, 10 1 and 10 2 bands were analysed on the basis of a model Hamiltonian developed by Watson for tetrahedral molecules. Spectroscopic constants were determined via computer simulations and relations for intervals between heads of branches. Spin-orbit coupling, Coriolis interaction and Jahn-Teller distortion in the lower electronic state were found to be relatively small but to show a vibrational dependence on v 1.
