13C NMR spectroscopy of polycyclic aromatics. VIII—amino derivatives of quinoline,isoquinoline, acenaphthene and fluoranthene

Complete assignments of the ¹³C n.m.r. spectra have been made for 5-aminoquinoline, 5-aminoisoquinoline, 5-aminoacenaphthene and 3-aminofluoranthene. Substituent-induced shifts are compared with those of the structurally related 1-aminonaphthalene. Some deviations within the series can be interpreted in terms of an increase of the exocyclic peri angle. An analysis of the ¹H n.m.r. spectrum of 3-aminofluoranthene is also given.
