Question

Krypton core The Co* cation has a ground state term symbol of 4F 9/2 What are the term symbols of the excited states that can be reached from this ground state based on the normal selection rules for atomic transitions. In the emission spectrum of Aluminum, there are two closely spaced lines at 25354.8 cm - and 25242.7 cm 1. These correspond to an excited state that is doublet S at n=4. There are three 1 and 32332 7cm-1 Thace correcnond to n doublet
