13C NMR Chemical Shifts in Selected Hydroaromatic and Aromatic Hydrocarbons

During the course of an extensive and continuing investigation of the structure of liquid and soluble products and derivatives of coal, the need for a collection of 13C NMR spectra of pure compounds which contain structures thought to be present in coal arose. For this purpose, 13C NMR spectra of a large number of hydrocarbons and heterocyclic compounds were obtained and analyzed or partially analyzed. Several phases of these spectral investigations have been previously published(1–4); the work reported here is primarily concerned with hydroaromatic compounds and with aromatic compounds, such as indan, which contain one partially saturated five-membered ring. To aid in the spectral analyses, chemical shifts of several methyl and ethyl benzenes were measured.
