在4600-5700A范围内观察到了YBF分子的三个吸收和发射系统。振动分析表明，跃迁来自一个共同的低态，假定为基态。本文对A2-X系统的0-0带进行了转动分析，并对另外两个0-0带进行了部分分析。174YbF的观察状态的分子常数(cm-1)总结如下：[图省略]。基态的Re值为2.016 A。
Three systems of the YbF molecule have been observed both in absorption and emission in the region 4600 to 5700 A. A vibrational analysis shows that the transitions arise from a common lower state, assumed to be the ground state. A rotational analysis of the 0–0 band of the A2–X system, together with partial analyses of the other two 0–0 bands are presented in this paper. Molecular constants (cm–1) for the observed states of 174YbF are summarised below: [graphic omitted]. The value of re for the ground state is 2.016 A.
