| 摘 要： | 本文报道草酰氯C2O2Cl2在358—372.5nm范围的激光诱导荧光(LIF)激发谱。对60多条振动谱带进行了归属,其中24条是吸收光谱中没有的。由振动结构得到C2O2Cl2分子在X基态和?激发态的部分振动频率,其中v＂7=84cm-1和v＇7=164cm-1是新的数据。对401振动带的转动结构的分析给出转动常数A=0.190cm-1,B=0.114cm-1,C=0.048cm-1。

| Abstract: | Laser-induced fluorescence excitation spectrum of oxalyl cholride (C2O2Cl2) in the rang of 358-372.5nm has been observed. More than 60 vibrational transitions have been assigned, in which 24 bands were not found in absorption spectrum. From the vibrational structure, we obtained some of the vibrational frequencies in ground state and excited state in which v＂7=84cm-1 and v＇7= 164cm-1 are new data. The rotational analysis of high resolved 401 band leads to the rotational constants A = 0.190cm-1, B = 0.114cm-1, and C = 0.048cm-1. |
