## Abstract PMR studies of a series of 2,4‐ and 2,6‐ dinitrophenyl‐ and 2,4‐dinitronaphthyl‐ aryl ethers strongly indicate the existence of preferred conformations. Extensive conjugation of the ether linkage with the dinitro ring, resulting in their coplanarity, is an important stereochemical influ

## Abstract A novel type of interannular coupling (^6^__J__~H,F~ = 1.0 to 1.3 Hz) has been observed in some fluorodinitrodiphenyl ethers between the fluorine(s) on one ring __ortho__ to the ether linkage and a proton __ortho__ to it on the other ring. ^1^H and ^19^F chemical shift and coupling cons
