## Abstract An accurate measurement of the chemical shifts and the coupling constants of some disubstituted acetophenones has been made. The acetophenones studied contained nitro, bromo or amino groups substituted in either the 3,4 or 2,5 positions. For compounds with no substituent adjacent to the
## Abstract The structures of the atropisomers of __o__βhexaphenylene are confirmed by their proton magnetic resonance spectra. The centrosymmetrical isomer **1a** gives rise to an AAβ²BBβ² spectrum, whereas the helical isomer **1b** displays an AAβ²BBβ² spectrum for two of its aromatic rings and an AB
