INEPT Inverse Detection

Detect on H, but get the signal that tell chemical shift of C13 spin 

Show the phase of this sequence

Passive / Active Spins

Jbc > Jac

Show the coupling between these shape of the peaks? Absorption or dispersion? In-phase or anti-phase?

TOCSY

Show the evolution from Iz to Sz and show that IzSz does not evolve.

Do stimulated echo for IS spin system

Show that this sequence is a perfect pi pulse
