## Abstract Inter‐proton long‐range and ring couplings were measured in __o__‐anisaldehyde and in seven disubstituted anisoles. In order to investigate the transmission mechanisms of long‐range couplings with the methoxy group, partially restricted molecular orbital (PRMO) calculations were carried

## Abstract Double and triple nuclear magnetic resonance experiments performed at 100 MHz demonstrate the existence of long range ^1^H—^1^H couplings through epoxides. In a series of epoxycontaining sesquiterpenoids, interactions between protons separated by up to six sigma bonds were detected. The
