Is there any shortcut method by which we can find the atomic term symbols ignoring the spin-orbit coupling, i.e. ignoring the values of J.
For instance, when writing the d-d transitions for any complex, we write the atomic term symbols and them split them further into other states. I know the lengthy procedure to find the term symbols by considering the values of Ml, and finding the exact states including the spin-orbit coupling but is there a shortcut way by which we may find the atomic term symbols?
Like, in the above picture, how did we find the terms for d2 to be 1S, 1G, 3P, 1D, and 3F
