Thanks for your efforts,tk.

As I said, I studied the Bohr model thoroughly, I only want to check what are the differences with the QM model.

To avoid further misunderstanding ,I'll'ask specific questions so you (

*or exchemist or anyone*) can give me simple answers, and I'll learn what I am looking for:

1- can you show me how you get

** B*** (2p)* = 0.4 T working backward from the spectral lines i.e. 656.3 +/- 0.016 nm, 1.88913 +/- 0.0000455 eV?
