Spectroscopic investigations of descloizite

Spectroscopic investigations of fluoroquinolones metal ion complexes.

The complex formation reaction, between fluoroquinolones (FQ): ciprofloxacin (CPX), enoxacin (ENX), enrofloxacin (ENRX), lomefloxacin (LOMX), levofloxacin (LEVX), ofloxacin (OFX), norfloxacin (NFX), sparfloxacin (SPRX) and aluminum(III), iron(III), copper(II) and zinc(II) ions were investigated. The spectrophotometic titration method in a wide range of pH was utilized for estimation of complex ...

Spectroscopic and photometric investigations of MAIA candidate stars

Including our own observational material and the Hipparcos photometry data, we investigate the radial velocity and brightness of suspected Maia variable stars which are classified also in some examples as peculiar stars, mainly for the existence of periodic variations with time-scales of hours. The results lead to the following conclusions: (1) Short-term radial velocity variations have been un...

Synthesis and Spectroscopic Investigations of New Linear Heterobimetallic Clusters

Z. Naturforsch. 55 b, 238-242 (2000); received Oktober 10, 1999 IR Data, Chalcogenides, Molybdenum, Tungsten Red-brown crystals of a new bis(thiomolybdate) complex [Me4N]3[(MoOS3)2Ag] were formed at room temperature through the reaction of a solution of [Me4N]2[MoOS3] in MeCN with solid AgCN. They are monoclinic, space group P2i/c with unit cell parameters a = 16.662(9), b = 9.464(3), c = 17.89...

Spectroscopic and Kinetic Investigations of Conjugated Bi Radical Intermediates

Several reactive biradical intermediates of photochemical reactions were monitored directly in solution by the technique of kinetic and time—resolved spectrographic laser flash photolysis, and identified with the aid of low—temperature epr and optical spectroscopy, semiempirical calculations, as well as conventional steady—state analyses of product distributions. The focus of this report is on ...
