A　full　IR,　UV-Vis,　FIR,　spectroscopic　analysis　on　substituted　porphyrin　iron,　manganese,　cobalt,　copper　and　Zinc　complexes　was　performed,　and　the　spectroscopic　patterns　were　found　for　the　metalloporphyrin　compounds　with　various　structures.　Base　on　molecular　structures　theory,　the　reasons　for　the　spectroscopic　patterns　were　discussed　deeply.　Considering　the　inconsistency　of　the　far-infrared　spectra　of　the　Fe-Cl　axial　bonds　in　chloro-iron　tetraphenylporphyrins　reported　in　the　literature.　Their　far-infrared　absorptions　were　investigated　by　using　both　theoretical　analysis　and　experimental　determination,　and　the　results　showing　that　their　vibrational　frequencies　of　the　Fe--Cl　bonds　in　different　substitution　chloro-iron　tetraphenylporphyrins　were　associated　with　their　structures,　and　were　linearly　related　to　the　length　of　Fe--Cl　bonds.
