采用从头算的偶合族理论和组态相互作用方法对NH, NO, HNO 自由基的基态结构进行研究, 借助多体项展式理论导出HNO 自由基的势能函数并绘制了等值势能图. 首次报道了HNO 自由基对称伸缩振动和旋转势能图中, 在O+NH→HNO, H+NO→HNO, N+HO→HNO 反应通道上都有鞍点出现, O 原子需要越过1.153 eV 的能垒, H 原子须克服1.683 eV 的能量, N 原子须克服2.126 eV 的能量才能生成稳定的HNO 自由基. 同时也首次报道了HNO(X1A’)自由基的同分异构体HON(X3A") 在势能曲线中的位置及HNO↔HON 转变所需的能量.The ab initio coupled-cluster theory and the configuration interaction method have been used to optimize the possible ground state structures of NH, NO and HNO. The potential energy functions of HNO have been derived from the many-body expansion theory. In the symmetric stretching vibration and rotation potential energy diagram of HNO, there are saddle points in reaction kinetics O+NH→HNO, H+NO→HNO, N+HO→HNO, when O, H, N atoms with the energies surpassing 1.153 eV, 1.683 eV, 2.216 eV respectively, a stable HNO molecule could be formed. These are reported for the first time so for as we know. In addition, It is reported that the position of HNO’s isomer in the curve and the energy of transition from HNO to HON are also determined.
