1. The problem statement, all variables and given/known data (Q1) Which transition will produce a normal zeeman triplet in a weak applied field? (Q2) The sodium resonance line is a doublet. What is the total number of components that appear when the line is split by a weak applied field? 3. The attempt at a solution (Q1) 1D2 --> 1P1 or 2P(3/2) ---> 2S(1/2) ?
