| 英文摘要 | Raman spectra of purified oxygen evolution core complexes (pd oecc) thin films on silver mirror substrates have been taken over the frequency range of 250 - 3100 cm(-1) by surface enhanced raman scattering (sers), besides the fundamental frequency modes of beta -carotene in pd oecc, many weak peaks are observed. according to the selection rules of overtone and combination bands, most of them are attributed to the second-order raman spectra of beta -carotene. compared with the sers of normal pd oecc, the sers of pd oecc after strong illumination shows a decrease in scattering intensity and an increase in line widths, indicating changes of conformation and micro-environment of beta -carotene. the results of sers are consistent with the changes of absorption spectrum of pd oecc induced by strong illumination. there are no changes that can be ascribed to new vibration bands, so it is deduced that pd oecc on the silver mirror is identical to that in the solution. in summary, sers proved a good method to study the photodamage mechanism of photosynthesis. |
