Circular Dichroism of Light-harvesting Complexes from Purple Photosynthetic Bacteria*
The CD spectra of a range of antenna complexes from several different species of purple photosynthetic bacteria were recorded in the wavelength range of 190 to 930 nm. Analysis of the far UV CD (190 to 250 nm) showed that in each case except for the B800-850 from Chr. vinosum the secondary structure of the light-harvesting complexes contains a large amount of a-helix ( 2 5 0 % ) and very little...
متن کاملMagnetic circular dichroism of porphyrin lanthanide M3+ complexes.
Lanthanide complexes exhibit interesting spectroscopic properties yielding many applications as imaging probes, natural chirality amplifiers, and therapeutic agents. However, many properties are not fully understood yet. Therefore, we applied magnetic circular dichroism (MCD) spectroscopy, which provides enhanced information about the underlying electronic structure to a series of lanthanide co...
متن کاملShape-conserving enhancement of vibrational circular dichroism in lanthanide complexes.
The VCD spectra of lanthanide chelates with two chiral ligands display conserved sequences of bands throughout the Ln series. Some compounds (Tm, Yb) feature increased bands and strongly improved signal-to-noise ratios, an effect we dub Lanthanide Induced VCD Enhancement (LIVE).
متن کاملMicroscopic measurement of circular dichroism spectra.
A microscope device to measure the circular dichroism (CD) spectra of a specified microscopic region of chiral samples was constructed by combining of a couple of objective lenses and a CCD camera, which was installed in a sample chamber of a commercially available CD spectropolarimeter. By using this apparatus, high quality micro-CD spectra in the 60 x 60 microm region of samples could be meas...
متن کاملSelected deoxyoctanucleotides and their daunomycin complexes: Infrared absorption and vibrational circular dichroism spectra
The infrared absorption (IR) and vibrational circular dichroism (VCD) spectra are reported for six self-complementary deoxyoctanucleotides complexed with the anthracycline drug daunomycin. The oligomers included d(CGCGCGCG) d(CGCGCGCG), d(CGCATGCG) d(CGCATGCG) and d(CGCTAGCG) d(CGCTAGCG), which possess a 50CGC triplet, and d(CGATATCG) d(CGATATCG), d(CGTATACG) d(CGTATACG) and d(CGAATTCG) d(CGAAT...
