I am really confused by the ground state part of the question. I was planning on using the equation
Ejj^mI = -(mu mI Bhf) /I
to calculate Bhf which could then be used in the
EfhmI+1 – EhfmI
equation to calculate gI. On the data website, the energy of the ground state is given to be 0 and since neither mu, I, or mI are zero, this means that Bhf must be zero? This is then a dead end as you cannot meaningfully use Bhf=0 in the next eqn.
Can somebody please point out what I have done wrongly? I considered using the B(0) equation however this raised the question of what to use as the wavefunction?
