Using a time-dependent-density functional theory (TD-DFT), Configuration Interaction Singles (CIS) and Zerner’s Intermediate Neglect of Differential Overlap (ZINDO) methods, we have investigated the UV-Visible spectra of one new intramolecular cyclization at before and after intramolecular attack. All structures were optimized at the B3LYP/6-311++G** level while UV-Visible parameters were calcul...

The synthesis and characterization of the isomeric ruthenium complexes with general formula cis- trans-[Ru(trpy)(qc)X]n+ (trpy is 2,2':6',2?-terpyridine, qc 8-quinolinecarboxylate, cis-1 trans-1, X = Cl, n 0; cis-2 trans-2, X=OH2, 1) respect to relative disposition carboxylate ligands are reported. For comparison purposes, another set trans-[Ru(trpy)(pic)(OH2)]+ (pic 2-picolinate (cis-3, trans-...

The aim of the present study was to determine chemical analysis, antimicrobial and antioxidant effects Eurhynchium angustirete (Broth.) Isothecium alopecuroides (Lam. Ex Dubois) essential oil obtained by distillation method (Clevenger apparatus hydrodistillation). Obtained volatile oils were identified gas chromatography-mass spectrometry (GC/MS) which revealed presence twenty-two components an...
