Question

possible transition in d2 configuration?
​

Answer 1

Answer:

Depending of the d-number of the cation, two different transitions are possible; the t2g to π* and eg to π* may both be observed. Metal to Metal charge transfer: Some compounds possess metal ions in two different oxidation states.

Answer 2

Explanation:

45 microstates

determining the free ion states from the atomic configurations xsn(x+1)pn is complex! each of the terms, thus for the 3P term L=1 and S=1 leading to J=2, 1, 0 and the term symbols are 3P2, 3P1 and 3P0. o for example for d2 there are 45 microstates which are divided into the terms shown in Figure 2.
