Band assignment in hemoglobin porphyrin ring spectrum: using four-orbital model of Gouterman.
نویسندگان
چکیده
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.

ELECTRONIC STRUCTURES AND ABSORPTION SPECTRA Gouterman Four-Orbital Model
Martin Gouterman first proposed the four-orbital model in the 1960s to explain the absorption spectra of porphyrins [17, . According to this theory, the absorption bands in porphyrin systems arise from transitions between two HOMOs and two LUMOs, and it is the identities of the metal center and the substituents on the ring that affect the relative energies of these transitions. The HOMOs were c...
متن کاملExcited states of porphyrin isomers and porphycene derivatives: a SAC-CI study.
Excited states of free-base porphyrin isomers, porphycene (Pc), corrphycene (Cor), and hemiporphycene (hPc), were studied by the Symmetry-Adapted Cluster (SAC)/SAC-Configuration Interaction (CI) method. The absorption peaks of the porphyrin isomers were assigned on the basis of the SAC-CI spectra. The X, Y, X', and Y' bands of the porphyrin isomers, which have weak intensities, are identified. ...
متن کاملSpectroscopic and computational study of β-ethynylphenylene substituted zinc and free-base porphyrins.
A series of tetraphenylporphyrins appended at the β-pyrrolic position with an ethynylphenylene- or ethynylpyridine-substituent have been subjected to spectroscopic and density functional theory (DFT) analyses. The mean absolute deviation between corresponding experimental and DFT-derived vibrational spectra is up to 10.2 cm(-1), suggesting that the DFT B3LYP/6-31G(d) method provides an accurate...

We report here spectroscopic and theoretical (AM 1) studies on zinc(I1) octa-B-halotetrakis(pentafluoropheny1)porphyrins (ZnTFPPX,; X = C1, Br) that show a red shift in the Soret and Q absorption bands attributable to substituentinduced saddling of the macrocycle. The electronic effect of the halogens is to reduce the energies of both the HOMOs and LUMOs; however, this stabilization of orbital ...

Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra ...
