The UV-visible electronic spectra of some azo dyes have been studied. The different bands observed in the electronic spectra of the compounds in various organic solvents have been assigned to the proper electronic transitions. The solvatochromic behaviour of these compounds was investigated by studying their visible spectra in several pure and mixed organic(More)
The adsorption of carbon monoxide on the surface of graphene and aluminum doped graphene is studied using density functional theory. The adsorption energies have been calculated and compared for different configurations of the molecule on the surface. For each configuration the relaxed atomic coordinates were determined by calculating the local minimal of(More)
In this work, UV-Vis. electronic spectra of 1-pyridinyl-2-methylene-benzene carbohydrazonic acid (L) have been studied. The different bands observed have been assigned to the proper electronic transitions. The solvatochromic behavior of this compound is investigated by studying their electronic spectra in organic solvents with different polarities. The(More)
