WebAbstract. Valence bond theory is used to calculate π-electron spin densities (ρ i) on carbon atoms in the perinaphthenyl free radical, [Complex chemical formula] The results are ρ 1 =—0.176, ρ 2 =+0.321, ρ 3 =—0.220, ρ 13 =+0.262. The theoretical spin densities ρ 1 and ρ 2 are compared with the ``experimental'' values ρ 1 =0.098, ρ 2 =0.325 which are obtained … WebAbstract. Progress has been made in the understanding of potential energy surfaces for unimolecular ion dissociations and ion-molecule reactions. With recent advances in instrumentation, many new techniques have been developed to generate and study ions, ion-molecule complexes, and large ionic clusters. Developments in ion spectroscopy have ...

WebWe have now found that another organic radical, perinaphthenyl (or phenalenyl, compound I in Fig. 1) is also formed in a variety of flint samples. ESR spectra provide an unambiguous … WebPerchloric acid is the strongest mineral acid but at or- dinary temperatures its oxidising power is less than that of the other oxygen acids of chlorine, bromine, and iodine1. In many organic solvents perchloric acid is readily sol- vated and this changes the polarity of the bond between the hydrogen atom and the C1O 4 residue. WebIn this study, we present the transition from simple aromatic molecules to the complex ortho-bridged bi- and tri-cyclic hydrocarbons, e.g., CH 2 + mono-substituted naphthalene … tritch buonocore law
