摘要: CH3NO(1)、CH2FNO(2)、CHF2NO(3)、CH2ClNO(4)、CHCl2NO(5)、CHCIFNO(6)、CF3NO(7)和CCl3NO(8)是一类重要的光化学分子,它们稳定性差、寿命短,实验研究其结构及稳定性较困难,仅CH3NO、CF3NO和CCl3NO分子有理论研究,其余均未见报道。

Abstract: The stabilities of the molecular structures of CH3NO, CH2FNO, CHF2NO, CH2ClNO, CHCl2NO, CHFClNO, CF3NO and CCl3NO was studied at minimal basis set(STO-3G) by complete optimization and the rotation potential barrier of CF3NO at the extended basis set(4-31G). The quite satifactory results have been obtained.
