Abstract: | Bond dissociation energies for removal of the nitrogen dioxide moiety in nitrobenzene and 3-amino-nitrobenze,4-amino-nitrobenze and 1,3-dinitrobenzene and 1,4-dinitrobenzene and 2-methyl-nitrobenzene and 4-methyl-nitrobenzene and 1,3,5-trinitrobenzene nitroaromatic molecules,are calculated using the three hybrid Density Functional Theory(B3P86) methods with 6-311G** and 6-31 G** basis set,respectively.By comparing the computed energies and experimental results,it is find that the B3P86/6-31G** method is able to give the best agreement with experimental values for these nitroaromatic molecules. |
