Question:

Draw sketches, roughly to scale, of the multiplets represented by the following operators:

and

assuming that the couplings constants are:
(a) J12 = 2Hz, J23 = 6 Hz; and
(b) J12 = 6 Hz, J23 - 6 Hz. Label each line of the multiplet according to the spin states of the passive spins. (You should assume that y-magnetization gives rise to an absorption mode lineshape.)
