The sign of the four-bond FH coupling in methoxyflurane
The methoxyflurane NMR spectrum was reexamined looking for a through-space transmitted four-bond FH coupling. This coupling was measured and its sign determined relative to the corresponding vicinal FH coupling. This sign determination required a triple irradiation technique, which is also described...

| Sumario: | The methoxyflurane NMR spectrum was reexamined looking for a through-space transmitted four-bond FH coupling. This coupling was measured and its sign determined relative to the corresponding vicinal FH coupling. This sign determination required a triple irradiation technique, which is also described. A Karplus-like equation for the vicinal FH couplings yields the relative populations of both preferential conformers, and determines the positive sign of both three- and four-bond FH couplings. © 1986. |
