The effect of charge transfer reactions on analyze excitation and ionization in the inductively coupled plasma was studied by two independent techniques. In one technique, pulsed lasers were used to either deplete the ground states of the singly charged ion. In both cases the perturbed species were collision partners with argon in potential charge transfer reactions. The effects of charge transfer collisions could be detected in the form of changes in emission from product species. In the second technique, a simple correlation method was used to detect the link via charge transfer of neutral atom ground states and highly excited ion levels. In the presence of charge transfer collisions, the populations of such linked levels show strong positive correlation's. The two techniques were used to study the effects of charge transfer reactions on third row elements Ca-CU. With the exception of Cr and Mn, all of the elements studied showed positive evidence of excitation and ionization by charge transfer sollision with argon.
