摘要
确定了室温下NO2 分子在 5 2 4 - 5 2 9.5nm区域的 5个新振动带 ,并分析了每个振动带的转动结构 ,确定了这些带的带源、转动常数以及旋 -转耦合常数等分子常数 ,实验结果表明 ,所有得到转动标识的谱线均属于平行跃迁 。
Using the dye laser pumped by the excimer laser, the high-resolution fluorescence excitation spectrum was measured in the region 524-529.5nm at room temperature.We determined the molecular constants such as band origins and rotational and spin-rotation constants for 5 new vibronic bands in the region. It was shown from the experiment that all rotational structures analyzed are of the parallel type, and there are strong interactions between the electronic excited state A～ 2B 2 and the high lying vibration levels of ground state X～ 2A 1.
