Question:

The pulse sequence for a constant time version of double-quantum filtered COSY is shown below.

Show that, for a two-spin system and starting from z, the double quantum present between the final two pulses is given by

Determine the effect of the final pulse on this double-quantum state, and hence predict the form of the diagonal- and cross-peak multiplets. Does double-quantum filtration have any practical benefits in this experiment?
