Abstract

We utilize the internally contracted explicitly correlated multireference configuration interaction (icMRCI-F12) method, incorporating the Davidson correction, to perform comprehensive ab initio studies on the FNO molecule. The vertical transition energies and the oscillator strength are calculated for 14 electronic states of FNO. For the first time, the potential energy curves of these states are examined along the F–N–O bond angle, N–O, and N–F bond distances, respectively. On the basis of these computational results, we discuss the dissociation mechanism of the FNO molecule in the ultraviolet region. Our findings will provide valuable insights into the electronic state behavior and photodissociation of halogenated nitrenes.

FNO分子结构和电子激发态的理论研究。
我们利用内部收缩显式相关多参考构型相互作用(icMRCI-F12)方法,结合戴维森校正,对FNO分子进行了全面的从头算研究。计算了FNO 14个电子态的垂直跃迁能和振子强度。首次分别沿着F-N-O键角、N-O键和N-F键距离考察了这些态的势能曲线。在这些计算结果的基础上,我们讨论了FNO分子在紫外区的解离机理。我们的发现将为卤化亚硝基烯的电子态行为和光解提供有价值的见解。
