Abstract
Nuclear Overhauser effect difference spectroscopy has been used to define the structures of two porphyrins isolated from Julia Creek oil shale as nickel(II) 3,4-didehydro-3,9,14-triethyl-4,8,13,18-tetramethylphorbine (DPEP) and its (9-desethyl homologue, thereby providing support for the hypothesis that petroporphyrins originate from chlorophyll.Keywords
