A Theoretical Study of the OH + HN2 Reaction

Abstract

The singlet potential surface of the OH + HN2 reaction has been investigated at the B3LYP/6-311++G (3df, 3pd) level. The single-point energy calculations are performed at the high-level CCSD (T) / 6-311++G (3df, 3pd) for more accurate energy values. DFT calculations show that the most favorable association way starts with a barrierless addition of the OH to HN2 leading to HNN-OH (im6). The adduct im6 goes through an H shift from N atom to O atom, forming the product of H2O and N2.
