Abstract:
Laser-induced fluorescence excitation spectra of jet-cooled NiCl molecules were recorded in the energy range of 12900-15000 cm-1. Six vibronic bands with rotational structure have been observed and assigned to the [13.0]2П3/2(v'=0-5)-X2П3/2(v"=0) transition progres-sion. The relevant rotational constants, significant isotopic shifts, and (equilibrium) molecu-lar parameters have been determined. In addition, the lifetimes of the observed bands have also been measured.
Key words:  NiCl, Laser-induced fluorescence, Isotopic shift

摘要:
采用激光诱导荧光技术在12900-15000 cm-1能量范围内研究了超声射流冷却条件下的氯化镍光谱. 通过分析,6个具有转动结构的振转带被归属为跃迁序列. 相关的转动常数、同位素位移以及(平衡)分子常数被确定. 此外, 还测量了这些振转带的寿命.
