✦ Synopsis

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 with reasonable accuracy on the basis of the ringcurrent.. model of Pople applied to fluorene and acenaphthene, which form the chief componenti of the pitches normally encountered.
