Abstract: The NO dimer cation, (NO)2+, has been studied by using density functional theory. The geometries and the harmonic vibrational frequency of (NO)2+ have been calculated at B3LYP/ 6-311++G* level. The results indicate that there are five stable doublet states. The ground state is determined to be the trans isomer with N-N bond linkage, which has C2h symmetry. The relative stability of all stable geometric structures has been analyzed. The state-state correlation and the isomerization mechanism are predicted by searching the transition states and using the same methods.

Key words: NO dimer cation, Density function theory, Transition state
