The Absorption and Magnetic Circular Dichroism Spectra of Matrix-Isolated Os1804 and 0s1604 ROGERGRINTER
ثبت نشده
چکیده
Matrix absorption and magnetic circular dichroism studies on 0s160, and OS’804 have been carried out to clarify the number of electronic transitions present in the region. The spectra show that the irregular vibrational structure in the I60 species with its onset at -276 nm is perfectly regular in the “0 compound. The system is, therefore, interpreted as a single electronic system analogous to that observed in the permanganate ion. The Raman spectrum of Os?O, single crystal has also been obtained.

In vitro study of drug-protein interaction using electronic absorption, fluorescence, and circular dichroism spectroscopy
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...
متن کاملX-ray absorption and magnetic circular dichroism of graphene
We present systematic investigations of the electronic and magnetic properties of the graphenel Ni( Ill) system by means of x-ray absorption spectroscopy (XAS) and magnetic circular dichroi sm (XMCD) at the Ni L2,3 and C K absorption edges. The XAS CIs -> 1/'* , u* spectra show dramatic changes as the angle, il', between the electrical vector of light and normal of the sample is varied reflecti...
متن کاملIntrinsic deviations in fluorescence yield detected x-ray absorption spectroscopy: the case of the transition metal L2,3 edges
Fluorescence yield (FY) detected x-ray absorption spectra (XAS) of 3d transition metal ions are calculated from the integrated 2p3d resonant x-ray emission spectra. The resulting FY-XAS spectra are compared with the normal XAS spectra corresponding to the absorption cross section and significant deviations between the two spectra are found. This implies that the assumption that the FY-XAS spect...

We have investigated the magnetic electronic structures of PtMnSb, NiMnSb, Ni2MnSb,MnSb, MnAlGe, and Mn2Sb by soft-x-ray absorption spectroscopy ~XAS! and magnetic circular dichroism ~MCD! measurements in the Mn 2p core absorption region. Different degrees of the electron itinerancy of the Mn 3d states are discussed. The large orbital angular momentum of the Mn 3d electrons is revealed for MnSb...
