If you had problems with deciding which proton groups show spin-spin
coupling, you might want to check page
90 for some additional explanations
If you recall the examples so far where spin-spin coupling occured
between groups of protons, then you should have no difficulties in
answering the following question:
| Under what conditions would you expect to see no
coupling between two given groups of protons in a molecule?
