Comparison of the Electronic and Vibrational Optical Activity of a Europium(III) Complex

Popis výsledku v původním jazyce

The geometry and the electronic structure of chiral lanthanide(III) complexes are traditionally probed by electronic methods, such as circularly polarised luminescence (CPL) and electronic circular dichroism (ECD) spectroscopy. The vibrational phenomenaare much weaker. In the present study, however, significant enhancements of vibrational circular dichroism (VCD) and Raman optical activity (ROA) spectral intensities were observed during the formation of a chiral bipyridine-Eu-III complex. The ten-foldenhancement of the vibrational absorption and VCD intensities was explained by a charge-transfer process and the dominant effect of the nitrate ion on the spectra. A much larger enhancement of the ROA and Raman intensities and a hundred-fold increase ofthe circular intensity difference (CID) ratio were explained by the resonance of the lambda = 532 nm laser light with the F-7(0) -> D-5(0) transitions. This phenomenon is combined with a chirality transfer, and mixing of the Raman and lum
