The studies on the belongings of the properties of mineral oxide made by dethroning of nanosized metal clusters on the group of chemical elements surfaces on the adsorption and binding of molecules of sole and pairwise NO2 on their surface are investigated by mass functional belief. In this work, we examined NO2 pair adsorption behaviour over the (MgO)9 and (CaO)9 surface clusters by taking everything in mind NO2 bind on cations making nitrite and NO2 binds on anions producing nitrates. In addition, vibrational ranges have been computed by way of the B3LYP hybrid mass functional so that define the experiments [J. Phys. Chem. B 2002, 106, 6358] particularly, concerning a transient 1225 cm-1 incorporation during growth of NO2 in MgO supported BaO. The standard of generality of results was proven by equating (NO2)x (MO)9 for x=1,2 and M=Mg, Ca. Finger prints are produced for the sole bidentate M2+-[ONO]--M2+ surface nitrite ion. A novel single monodentate [Ocluster - NO2]2- ion and the chemisorbed Nitrite/Nitrate ion pair, that is, M2+-[ONO]--M2+ + [Ocluster -NO2]-. The results showed, the novel monodentate [Ocluster - NO2]2-, expected responsible for the tentatively observed 1225 cm-1 incorporation, being a temporary towards surface nitrate rather than nitrite composition. This result is consistent accompanying a mechanistic DFT study concerning the beginning loading of NO2 in BaO. Furthermore, our results show the computed instability for a distinct adsorbed Nitrite is 0.36 eV and (1.66 eV) for Mg9O9 and (Ca9O9), while, pairs adsorption displays a 2.82 eV and (3.64 eV) stability. Hence, the adding of second NO2 causes a pronounced surface entertainment, which exchanged of bond lengths and bond angles.
