Abstract:
We measure the dispersed spectrum of the A2Π~X2Σ+ system of MgH using laser abla-tion/laser induced Fluorescence method and obtain the Frank-Condon factors and related transition frequencies of the A2Π(v′=0)-X2Σ+(v〞=0,1) system by analyzing the experimen-tal spectrum. Also, we calculate the Franck-Condon factors and transition frequencies of the A2Π~X2Σ+ system of MgH. A comparison of our theoretical calculation and experimental results with other reported theoretical results was carried out as well.

摘要:
利用激光消融/激光诱导荧光的方法测量了MgH分子A2Π~X2Σ+的色散荧光谱, 并通过分析实验光谱获得了MgH分子的A2Π(v′=0)~X2Σ+(v〞=0,1)跃迁的弗朗克-康登因子和相应的跃迁频率. 同时也用理论计算方法计算出MgH分子A2Π(v′=0)~X2Σ+(v〞=0,1)的弗朗克-康登因子和跃迁频率. 实验结果、理论结果和其他文献中的理论结果是一致的.
