Triplet excited states some organic molecules have a triplet (S = 1) excited state at an energy

Question:

Triplet excited states some organic molecules have a triplet (S = 1) excited state at an energy k_BΔ above a singlet (S = 0) ground state.

(a) Find an expression for the magnetic moment (μ) in a field B.

(b) Show that the susceptibility for T >> Δ is approximately independent of A.

(c) With the help of a diagram of energy levels versus field and a rough sketch of entropy versus field, explain how this system might be cooled by isentropic magnetization (not demagnetization).
