## Abstract The NMR spectra of a series of heterocyclic compounds analogous to anthracene have been investigated at 220 and 60 MHz. Correlations have been made with molecular geometry and parameters calculated from semiβempirical MO theory. For planar molecules, the chemical shift of the proton __o
The yield of quinoline-insoluble portion from pitches correlates well with the aromatic hydrogen content of the carbon disulphide-soluble fraction scaled up by proportion to the whole pitch, which therefore by implication is an indication of the binding properties. The chemical shifts are explained
