An electron diffraction investigation of the peri -bonds in perylene

The molecular structure of perylene has been studied in the vapour phase by the sector electron diffraction method. The average carbon-carbon bond distance in perylene apart from the peri -bonds was found to be about 0·010 Ǻ longer than the average carbon-carbon bond distance in the naphthalene molecule. The peri -bond length was determined to be 1·493 ± 0·015 Ǻ.

The object of this investigation was to get replies to the following questions concerning the structure of certain simple benzene derivatives in the vapour phase:— (1) Is the benzene ring a flat, regular hexagon? (2) What is the carbon-carbon distance in the benzene ring, and is this a constant independent of the number of substituents ?
