Experimental evidence of state-selective charge transfer in inductively coupled plasma-atomic emission spectrometry

摘要

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.
