Other Spectroscopic Methods for Probing Metal Centres in Biological Systems

Research output: Chapter in Book/Report/Conference proceedingChapter


While the earlier Chapters contained descriptions of the major techniques which can be used to study metalloproteins, there are a number of other approaches which can give valuable information in specific conditions. Thus, quite a number of metalloproteins are coloured and are therefore accessible to optical spectroscopic approaches. The electronic and geometric structures of metal centres in some metalloproteins are accessible to magnetic circular dichroism, which relies on the induction of optical activity by the application of a magnetic field. The energy of transitions between different vibrational levels promoted by the application of electromagnetic radiation of the correct frequency can also give valuable information, and in the second part of the Chapter some examples of vibrational spectroscopies (IR spectroscopy, Raman spectroscopy, notably Resonance Raman and surface-enhanced Raman scattering) are considered.
