13C NMR Chemical Shifts in Selected Hydroaromatic and Aromatic Hydrocarbons

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