title: Band assignment in hemoglobin porphyrin ring spectrum: using four-orbital model of Gouterman.
abstract: Band assignment for oxy, deoxy and methemoglobin using orbital promotion is crucial to understanding inter-relation of electronic transitions. Spectral changes may be correlated with conformational alteratiions. Conformational changes of hemoglobin were interpreted using four-orbital model of Gouterman. Our results indicated that Goutherman model can predict the predominant conformations of hemoglobin.
