Pyclen and cylen complexes of manganese show pH dependent catalase activity with improved TOF and TON for the more rigid pyclen derivative. Spectroscopic investigation shows O2 evolution corresponds with the presence of a μ-O bridged species.

Decomposition Schemes

Raman spectroscopy has been applied to the study of the pH-dependent decomposition of 12-molybdophosphoric acid, H3(PMo12O40), and 12-molybdosilicic acid, H4(SiMo12O40), in aqueous solution. The decomposition schemes involving several smaller polymeric molybdate species, proposed from indirect techniques such as electrochemistry, are confirmed. Identification of the species present in solution is made by comparison of the Raman spectra to the spectra of known species, except in the case of (PMo11O39)7-, for which the spectrum is reported for the first time.

Quantitative Estimates

It is necessary to have quantitative estimates of the intensity of lines (both absorption and emission) to obtain the physical parameters of the atmosphere of components.Some years ago at the Crimean observatory we began the spectroscopic investigation of close binary systems of the early spectral type with components WR, Of, O, B to try and obtain more quantitative information from the study of the spectra of the components.
