Figure 10.37

Note that the population differences across the I (1H) transitions are 4 (0.5[5 — (-3)] and 0.5[3 — (—5)]) and the differences across the S (13C) transitions are 1 (0.5[5 — 3] and 0.5[—3 — (—5)]). For a homonuclear system (e.g., 1Ha, 1Hb) the populations (diagonal elements) would be 2, 0, 0, and —2.

The density matrix representations of the 16 product operators for a heteronuclear two-spin system are given below.
