【摘要】 用441.56nm CW He-Cd⁺激光获得了³⁹K₂分子C¹Ⅱ_u→X¹∑_g⁺跃迁的碰撞诱导（CI）光谱。光谱分析表明:来自C¹Ⅱ_u（u′=0,J′=53）的碰撞诱导跃迁是P（△J=±2）、R（△J=±2）、Q（△J=±1）。碰撞诱导谱的波数计算值和实验值之间有令人满意的符合。研究了碰撞诱导（CI）伴线和激光诱导荧光（LIF）光谱主线的强度比ρ与缓冲气体压强、样品池温度的关系,给出了物理解释。更多还原

【Abstract】 The collision-induced spectra of C1∏u→X1∑q+ transition for 39K2 was obtained from 441.56nm line of CW He-Cd+ laser. The analysis of spectra showed that the collision induced transitions from C1∏u(ν’=0, J’=53)were P(△J=+2), R(△J=+2), Q(△J=+1). The calculated wave-numbers of collision-induced spectra were in agreement with the experimental values. The intensity ratio of collision-induced satellite lines and LIF parent lines versus buffer gas pressure, temperature of sample cell were studied andthe physical interpretation was given.更多还原
