DFT calculations at the BP86/TZ2P level have been carried out for the compounds OCBBCO, N(2)BBN(2), and [OBBBBO](2-). The calculations predict very short distances and large bond dissociation energies for the central B-B bonds. The nature of the bonding situation was investigated with...
The effects of a series of substituents on the electronic structure of the parent molecules were traced in their PE spectra and intercompared. The results for methyl, chloro, methoxy and cyano substitution a...
temperature. Bromine, like its neighbours chlorine and iodine in the periodic ( = of period ) table, has molecules made up of two atoms each. In these liquid elements, the molecules are close together, but not so crowded;they can pass lightly by one another.1.All elements are made up ...
