— The temperature dependence of the optical absorption bands and of the magnetic circular dichroism are measured for the Au" centre in KBr and RbCl. The data are analyzed with the method of moments by using six electron-lattice interaction coefficients to describe the coupling of the | 1 r l u > and | Tlu > excited states with the AXg, Eg and T2g lattice modes. The centre is found to be coupled...
Magnetic circular dichroism is used to investigate the evolution of ferromagnetism in the p-type magnetic semiconductor Ga12xMnx As. Local Mn moments and holes produce two spectroscopically distinct contributions, whose properties reveal an antiferromagnetic Mn-hole alignment in the ferromagnetic state. These components are present in both metallic and insulating samples with different temperat...
A user-friendly website for the analysis of protein secondary structures from Circular Dichroism (CD) and Synchrotron Radiation Circular Dichroism (SRCD) spectra has been created.
We generate angularly isolated beams of circularly polarized extreme ultraviolet light through the first implementation of non-collinear high harmonic generation with circularly polarized driving lasers. This non-collinear technique offers numerous advantages over previous methods, including the generation of higher photon energies, the separation of the harmonics from the pump beam, the produc...
human serum albumin (hsa) is an abundant, multifunctional and nonglycosylated negatively charged plasma protein. hsa ascribed ligand-binding and transport properties, antioxidant functions and enzymatic activities. in the present study, the interaction and side effects of a new designed anti-cancer compound (1,10-phenanthroline butyl dithiocarbamato palladium(ii) nitrate) on hsa have been inves...
Quantitative analysis of shadow X-ray Magnetic Circular Dichroism Photo-Emission Electron Microscopy
in the near future, design of a new generation of drugs targeting proteins will be required. considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. so far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. in these studies, use of spectroscopic method...
Spectroscopic studies with linearly or circularly polarized light of partially aligned molecular samples can provide two kinds of important information. One type of information is the molecular · alignment; the complete molecular orientation distribution function can not be found, but its essential properties can be determined, and these frequently enable a detailed interpretation of the spectr...
thermal conformational changes in human serum albumin (hsa) in present with a 10 mm phosphate buffer, at ph=7 have been investigated via circular dichroism (cd) and uv spectroscopic methods. the results indicate that temperature in a range of 25oc to 55oc could induce a reversible conformational change in the structure of hsa. the hsa phase transition corresponds to the physiological and pathol...
