Electron Distribution in Substituted Styrenes Derived from Infra-Red Spectra

13C NMR spectra of para-substituted meth

13C NMR spectra of para-substituted methoxybenzenes and phenols were recorded in the solid state to gain an insight into the manner and origin of substantial peak splittings in the ortho (up to 9.2 ppm) and mefa (up to 2.5 ppm) carbon signals. It was difficult to account for these peak splittings on
