## Abstract PMR studies of a series of 2,4β and 2,6β dinitrophenylβ and 2,4βdinitronaphthylβ 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
