(Table 5) Normalized average 14eV mass spectra of metalloporphyrin assemblages isolated from DSDP Holes 63-467 and 63-471@en

NiD, CuD refers to nickel or copper chelate of DPEP-series; NiE, CuE refers to nickel or copper chelate of ETIO-series; NiDiD refers to di-DPEP type porphyrin or alternately a dihydro-benz structure; NiBenz-D and NiDiBenz-D refers to porphyrin-nickel complexes with molecular weights equal to calculated benzporphyrin and dibenzporphyrin structure of the DPEP-series (note that NiBenz-D could also be a Ni di-Benz of the ETIO-series). Carbon Number [(m/z DPEP)/(m/z ETIO)] - Normalized spectra, highest ion abundance taken as 100.0, determined at 14eV.
