用电感耦合等离子体(ICP)-原子发射光谱法观察了Fe、Cr、Mn和Cu的状态选择性电荷转移行为。由于准共振电荷转移能级与附近能级的低效率碰撞混合，从Ar+到Fe、Cr和Mn的电荷转移具有状态选择性。这种低效率是由于核心电子的电子构型不同造成的。对铜的状态选择性电荷转移行为的原因尚不清楚，尽管对这种特殊情况提供了基于多重态内和多重态间混合效率的初步解释。
State-selective charge-transfer behavior was observed for Fe, Cr, Mn and Cu in inductively coupled plasma (ICP)-atomic emission spectrometry. Charge transfer from Ar+to Fe, Cr and Mn is state-selective because of inefficient collisional mixing of the quasiresonant charge-transfer energy levels with nearby levels. This low efficiency is the consequence of differences in electronic configuration of the core electrons. The reason for state-selective charge-transfer behavior to Cu is not clear, although a tentative explanation based on efficiency of intramultiplet and intermultiplet mixing for this special case is offered.
