| 摘 要： | 对气态氮化钒(VN)分子在光子总能量为56900～59020 cm-13∏0, v'=0)的单转动态， 然后再被紫外激光电离．这样的双色激光模式可以测量电子态、振动态和转动态都被选择和解析的氮化钒阳离子VN+(X2△; v+=0, 1, 2)光谱． 通过对转动解析的PFI-PE光谱模拟分析， 确定J+=3/2为基态离子态的最低转动能级， 从而确认VN+的基态电子态为2△3/2．通过对VN+(PFI-PE)光谱的分析得到如下物理量的精确数值：VN+(X2△3/2)的绝热电离能为IE(VN)=56909.5±0.8 cm-1(7.05588±0.00010 eV)，振动常数ωe+=1068.0±0.8 cm-1，反常振动常数ωe+χe+=5.8±0.8 cm-1；VN+(X2△3/2)的转动常数Be+=0.6563±0.0005 cm-1，αe+=0.0069±0.0004 cm-1，平衡键长为1.529 ?；VN+(X2△5/2)的转动常数Be+=0.6578±0.0028 cm-1，αe+=0.0085±0.0028 cm-1，平衡键长为1.527 ?；X2△5/2,3/2自旋轨道耦合常数A=153.3±0.8 cm-1
