摘要: 采用高灵敏度、高分辨率激光磁共振光谱(LMR)方法在6μm谱段测量了自由基分子NH2ν2带的π谱(ΔMJ=0).测量了前人已测过的谱,结果与之较好符合.并观测到了前人没有观测过的新谱,在3支激光谱线下共获得约13支塞曼(Zeeman)跃迁谱线,其中在2支激光谱线下新测得的谱线10支.利用我们已经测得的[8]σ谱的新的共振谱线的数值和已取得的激光磁共振谱线的标识方法,可预期得到NH2的一些新的分子参数.

Abstract: Using the method of CO intracavity laser magnetic resonance (LMR),we have detected the π(ΔMJ=0) transitions of ν2 band of free radical NH2.About 13 Zeeman components in 3 laser lines were detected,among them 3 Zeeman components in 1 laser line agree with the previous reported and 10 Zeeman components in 2 laser lines haven't been reported previously.
