摘要
在超声射流条件下观测了CS_2的激光诱导荧光R系激发谱(371—350nm),比常温情况下的光谱明显地简化了。对振动带系作了归属,并分析了其中几个带的转动结构。所得转动常数与前人数据作了比较.数据相当一致。推算出分子的转动温度降至15.6K。表明新建装置运转正常、有效.
R-system of fluorescence excitation spectrum (371—350 nm) of CS -1 cooled in a supersonic free jet is observed. the congestion of bands is eliminated significantly in contract to the corresponding spectrum at room temperature. The vibrational bands are assigned and the rotational structure of some bands are analyzed. the rotational temperature of the molecule in this case is cooled down to 15.6K.
