Assignment of the Fe-N epsilon (His) stretching mode in the resonance Raman spectra of a monomeric insect cyanomethaemoglobin.

Abstract:

:Resonance Raman (RR) spectra of the monomeric cyanomethaemoglobin CTT III from insect larvae of Chironomus thummi thummi are shown for the range of 200-550 cm-1. By iron and cyanide isotope exchange a line varying between 307 cm-1 for 57Fe-13C15N and 311 cm-1 for 54Fe-12C14N, has been assigned to the Fe-N epsilon stretching mode of this haem complex. The substitution of 54Fe for 57Fe has no effect on the Fe-C = N bending mode whereas it affects the Fe-CN stretching mode.
