| Abstract: |
| Laser-induced fluorescence excitation spectra of NiO have been recorded in the wavelength region of 510-650 nm under supersonic molecular beam conditions. More than fifty bands have been observed and rotationally analyzed to determine the molecular constants. The excited states exhibit highly irregular variations in terms of isotopic shifts, vibrational inter-vals, and rotational constants. Twenty-six bands attributed to [Ω=0, 1]-X3∑-0 transitions have been tentatively grouped into five vibrational progressions. Furthermore, dispersed fluorescence and lifetimes of the strong bands have also been measured. |

| 摘要: |
| 采用激光诱导荧光技术在510～650 nm研究了超声射流冷却下的氧化镍光谱，观测了55个振转谱带. 通过转动分析发现激发态的同位素位移、振转间隔和转动常数都表现出高度的不规则性，26个[Ω=0，1]-X3∑-0的跃迁谱带被暂时归属为5个振动序列. 此外实验中还观测了部分谱带的色散谱和寿命. |
