High-frequency shoulders on νs(CO) and νas(CO) bands in the FTIR spectra of an organometallic probe derived from tricarbonyl(1-4-η-5-pyridiniocyclohexa-1,3-diene)iron hexafluorophosphate have been observed on incubation with α-chymotrypsin and were assigned to an iron complex covalently bonded to enzyme-NH2 groups; curve-fitting analysis of the spectra enabled the bound complex to be detected even in the presence of an excess of the unbound probe and its FTIR spectrum to be calculated and compared with spectral data arising from similar interactions between the tricarbonyliron moiety and 12 amino acids and polylysine.
