Consider a hypothetical atomic emission transition of 2P 25, Draw an energy level diagram (including spin-orbit coupling) for the transition and indicate the allowed lines (25 is the lower state and for the 2P state energy increases with increasing J). If the observed transition wavenumbers for the transitions are 11729.51 cm! and 11758.95 cmL, assign the transitions and calculate the spin-orbit coupling constant in the 2P state
