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_ε{lunate} 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.
