Abstract:
Laser-induced fluorescence excitation spectra and dispersed fluorescence spectra of cobalt sulfide (CoS) have been recorded in the energy range of 22400-24400 cm-1 (corresponding to 446-409 nm). A new electronic transition progression with six vibronic bands, stemming from the X47/2 state of CoS, was identified and assigned to be [24.00]47/2-X47/2. The new observed 4△ state most probably originates from the core[10σ2][4π3][11σ2][1δ3][5π3] electronic configuration. Strong perturbations are found to extensively exist in the transition bands of this new state. The rotational constants and lifetimes of these bands have been determined

摘要:
采用激光诱导荧光技术在22400~24400 cm-1研究了超声射流冷却下的硫化钴光谱,获得了一个包含六个振动带的电子跃迁序列,该电子跃迁序列为:[24.00]47/2-X47/2.新的电子态的电子组态很可能是core[10σ2][4π3][11σ2][1δ3][5π3],该电子态的所有的振动谱带都受到了其他电子态的严重微扰,通过转动分析得到了这些谱带的转动常数,同时也测量了这些谱带的寿命
