In this work the molecules of 1,4- and 2,3-halo substituted 5,8-dinitronaphthalene were studied. Electrostatic potential maps were calculated for each of these molecules using the PBEPBE/6-311G** level of theory. The WFA-SAS program was used to obtain the maps of electrostatic potential. The dissociation energies of C – N bonds in the mentioned molecules were calculated using the SAPT program. Also, the heats of formation and the Widberg bond order were calculated. The results indicate that the halogens will have a much greater influence on the potentials above the central regions of the molecular surfaces in the case when they are located at positions 2 and 3 in 5,8-dinitronaphthalene. However, halogens in positions 1 and 4 lead to a significant decrease in the dissociation energy of C – N bonds, compared to 2,3-substituted analogues. It is believed that these differences are the results of different characteristics of the halogens, but also their positions in relation to the nitro gr...oups.
