Study of the Time-resolution Spectrum of theB3П1 Electronic State of InCI

Keywords： collision-free lifetime , relaxation rate constant , electronic transition moment , laser induced fluorescence

采用激光诱导荧光技术对InCl分子B3П1→X1∑+荧光光谱进行了分析和归属，并对 B3П1(v′=0)→X1∑+(v″=0)的时间分辨谱进行了观测．首次得到InCl分子B3П1态(v′= 0)无碰撞辐射寿命т0≈353 ns，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 B3П1 → X1∑+ transition of InC1 has been assigned and the time-resolution spectrum of (0,0) is measured by laser induced fluorescence. The collision-free fluorescence radiative lifetime τ0 ≈ 353 ns for the B3 П1(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.
