In order to distinguish essays and pre-prints from academic theses, we have a separate category. These are often much longer text based documents than a paper.
The preparations and properties of fifty-three new complexes of Cobalt (II), Nickel (II), Copper (II) and Copper (I) halides and nitrates are described. The ligands used were 3-Bromopyridine, 4-Chloropyridine, 1:2:4-Triazole, Quinoxaline, 2-Methylquinoxaline, 2:3-Dimethylquinoxaline, 2:3-Diphenylquinoxaline and Phenazine. The electronic reflectance spectra of these complexes have been measured, and the spin-allowed transitions assigned. The calculated ligand-field parameters are compared with those of related complexes, and the value of such calculations assessed. The spectra, along with confirmatory magnetic and infrared data are used to elucidate the stereochemistries of the complexes. [Continues.]
