摘要

本文利用激光诱导荧光光谱技术(LIF)、泵浦探测技术和简并受激超拉曼泵浦(DSHR)技术研究了高激发态分子Cs H(X1Σ~+v)与CO2的碰撞能量转移过程.精确测量了CO2(00~00)[J=36-60]与CO2(00~01)[J=5-31]的碰撞转移速率系数

并计算该过程的总猝灭率.这些实验数据表明CO2的转动平移能量对高位振动态碰撞能量的变化是非常敏感的.

Abstract

Using Laser Induced Fluorescence(LIF)

pump-dump-probe and Degenerate Stimulated HyperRaman(DSHR) technique

we have experimentally investigated the collisional energy transfer processes between the Cs H(X1Σ~+v) and CO2. The energy transfer rate constants of the CO2(0000) [J = 36-60] and CO2(0001) [J = 5-31] were accurately measured. The total quenching rates of this process was also precisely calculated. These data show that the rotational and translational energy gain in CO2 is much more sensitive to collisional depletion of excited Cs H.
