Abstract
Iron porphyries isolated from a Colorado bituminous coal have been investigated, and in favourable cases identified [etiohaem III, and the three suites (2),(3),(4) of its monodealkylation products], by the study of the paramagnetically shifted 1H NMR spectra of the low spin iron(III) dicyanide complexes.Keywords
