Resonance Raman Spectra

The carbonate radical (Co3−·) is of biological significance acting as an intermediate in free radical-mediated damage and is capable of oxidising amino acids and proteins. In order to distinguish between the four possible structures of Co3−·, nanosecond timeresolved resonance Raman (TR3) experiments were undertaken. Photolysis of persulphate at 250 nm generated the So4−· radical which then oxidised sodium carbonate. Resonance Raman spectra of the resulting Co3−· radical were obtained using a probe wavelength of 620 nm. Point group theory calculations and interpretation of the TR3 spectra suggest that the radical has C2v molecular symmetry.
