In this work, the processes of photodissociation of some diatomic molecular ions are investigated. The partial photodissociation cross-sections for the individual rovibrational states of the diatomic molecular ions, which involves alkali metals, as well as corresponding data on molecular species and molecular state characterizations, are calculated. Also, the average cross-section and the corresponding spectral absorption rate coefficients for those small molecules are presented in tabulated form as a function of wavelengths and temperatures. The presented results can be of interest for laboratory plasmas as well as for the research of chemistry of different stellar objects with various astrophysical plasmas.
在这项工作中，研究了一些双原子分子离子的光解离过程。计算了涉及碱金属的双原子分子离子的各个转动和振动状态的部分光解离截面，以及相应的分子种类和分子状态特征数据。此外，还以表格形式给出了这些小分子的平均截面和相应的光谱吸收速率系数，作为波长和温度的函数。所提出的结果不仅对实验室等离子体，而且对具有各种天体等离子体的不同恒星物体化学的研究都具有重要意义。
