摘要
采用激光诱导荧光技术对ＩｎＣｌ分子 Ｂ３∏１→Ｘ１∑＋荧光光谱进行了分析和归属，并对Ｂ３∏１（ｖ’＝０）→Ｘ１∑＋（ｖ＂＝０）的时间分辨谱进行了观测．首次得到ＩｎＣｌ分子Ｂ２∏１态（ｖ＇＝０）无碰撞辐射寿命 ０≈３５３ｎｓ；无辐射弛豫速率常数ｋＱ≈１．９８５×１０－１０ｃｍ３ｍｏｌｅｃ－１ｓ－１及电子跃迁矩｜Ｒｅ｜２＝ ０．４０Ｄ２．
The fluorescence spectrum of the B3∏2 - X1∑+ transition of InCl has been assigned and the time-resolution spectrum of (0,0) is measured by laser induced fluorescence. The collision-free fluorescence radiative lifetime 0≈353 us for the B3∏1(v' = 0), a quenching rate constant kQ ≈ 1.985 x 10-10 cm3molecule-1s-1 and the electronic transition moment |Re|2 = 0.40D2 are obtained for the first time.
