摘要
采用Herzberg的同位素理论研究了一氧化碳离子基态光谱性质的同位素效应,研究了同位素效应对分子结构性质在振动能级、力常数等方面的影响,得到了实验缺乏的13C16O+基态的光谱常数αe。结果表明,13C16O+基态与12C16O+基态的光谱性质较好符合Herzberg同位素理论的预计,振动能级、力常数理论预计非常接近实验结果。
The isotope effects of spectroscopy for Carbon monoxide is studied by using Herzbger＇s isotope theory. The isotope effect on the property of molecule structure in vibrational energy levels { Ev } and force constants { fn } are studied and compared with experimental results. The spectra data αe, absent in experiment, cab be obtained by using Herzbger＇s isotope theory. These results show that the vibrational levels and force constants of 12^C16^ O^＋ and 13^C16^O^＋ in X^2∑^＋ are better agreed with the results estimated by Herzbger＇s isotope theory. The obtained αe is credible.
