The effect of interaction of electron donor ammonia and pyridine molecules with sites on the properties of these ions, as well as the effect of adsorbed NO on the properties of interacting with has been followed in the present study.

It has been shown that the molecules NO interacting with which bonds pyridine or ammonia molecules were strongly activated (NO stretching band was shifted to lower frequency by 60-110 cm). This activation could be realized by the transfer of electrons from basic molecules via to antibonding * orbitals of NO. The significant NO activation took place when NO interacted with cations, which coordinated maximum possible number of molecules (). For this case the formation of complexes in which the transfer of full electrons from to antibonding * orbitals of NO occurred. Such strong activation of NO molecules by ammonia and pyridine molecules makes available the formation of . The fact that NO accepts electron forming and finally indicates that NO acts as oxidant in the presence of or . On the other hand, earlier IR study showed that without preadsorbed basic molecules NO acted as reducer: was reduced to whereas NO oxidized to .
