Electronic structure and spectroscopic properties of the low-lying electronic states of InCl and InCl have been studied from the ab initio based relativistic configuration interaction calculations. Spectroscopic constants (re, Te, xe) and potential energy curves of the electronic states of these species within 8 eV have been reported. Effects of the spin–orbit coupling on the electronic spectru...

Migration of charged compounds in micellar electrokinetic chromatography (MEKC) is based on micellar solubilization as well as electrophoretic migration. Consequently, the migration behaviour of these compounds can be described with a retention model or a mobility model. Both models are discussed and evaluated for the migration behaviour of monovalent weak acids in a sodium dodecyl sulphate mic...

Complexes of several transition metal ions with alpha-oximinoacetoacetyl pyridine-4-phenylthiosemicarbazone (H3OAPT) have been prepared. Attempts were made to elucidate their geometries by elemental analysis, molar conductance, magnetic measurements and by some spectroscopic (IR, ESR and electronic) techniques. All the investigated metal ions form mononuclear complexes except for CuII, which fo...

A compact ceramic high-temperature cell for Brillouin spectroscopy was designed and tested. The cell can be mounted onto a threeor four-circle goniometer and allows collection of the full set of elastic constants of minerals to temperatures in excess of 1500 K from samples with dimensions of 1003100320 mm or smaller. As a test of the instrument the single-crystal elastic constants of MgO were m...

Microwave spectroscopy, considered as the most definitive gas phase structural probe, is able to distinguish between different conformational structures of a molecule, because they have unique spectroscopic constants and give rise to distinct individual rotational spectra.Previously, application of this technique was limited to molecular specimens possessing appreciable vapor pressures, thus di...

A series of Cu(II), Ni(II) and Zn(II) complexes have been synthesized with newly synthesized Schiff base derived from 1,2-di(thiophen-2-yl)ethane-1,2-dione and 1,2-diaminoethane. The structural features have been arrived from their FT-IR, H NMR, C NMR, mass, UV-vis spectroscopic studies. The binding behaviours of the synthesis complexes towards calf thymus DNA have been investigated by absorpti...

background some herbal anticancer agents have direct interactions with dna. objectives the present study aimed to investigate the interaction of ctdna with rosemary flowers. materials and methods we used uv-vis, fluorescence and circular dichroism (cd) spectroscopic techniques. results the absorption of dna at 260 nm increased on addition of rosemary. herb extract quench the fluorescence of etb...

Transient absorption decay rate constants (kobs) for reactions of electronically excited zinc tetraphenylporphyrin ((3)ZnTPP*) with triruthenium oxo-centered acetate-bridged clusters [Ru3(μ3-O)(μ-CH3CO2)6(CO)(L)]2(μ-pz), where pz = pyrazine and L = 4-cyanopyridine (cpy) (1), pyridine (py) (2), or 4-dimethylaminopyridine (dmap) (3), were obtained from nanosecond flash-quench spectroscopic data (...

A theoretical description of the electronic states of the SBr radical at a high level of correlation effects treatment is presented for the first time. Most of its potential energy curves have a repulsive nature, but a set of bound (2)Pi states should provide a means for the experimental characterization of this species. The ground state can support over 40 vibrational states, but transitions f...

We report the preparation and the spectroscopic properties of Langmuir-Blodgett films obtained by mixing in the same monolayer a polar amphiphilic octadecyl tetracyanoquinodimethane (Cj~TCNQ) and an ionic semi-amphiphilic (Cj~s~dithiolium-TCNQ compound. A cluster approach is used for the interpretation of the electronic charge transfer band and of the vibronic features in infrared as a result o...
