摘要
激光磁共振光谱方法被用来研究NO_2的v_3振转带谱线的线宽及压致增宽。通过实验测量及数据分析得到了NO_2的自增宽系数及外来气体N_2O_4和CO_2对它的压致增宽系数,γ_(NO_2-NO_2N_2O_4CO_2)=0.043±0.005,0.014±0.003,0.013±0.003MHz/Pa(HWHM),并由此得到了相应的碰撞截面。这些参数的获得对大气污染监测具有十分重要的意义。
Laser magnetic resonance (LMR) spectroscopy technique was used to study the linewidth and pressure broadening of the spectral lines of v3 band of NO_2. The pressure broadening coefficients r^0_(NO_2-NO_2,N_2O_4∞_2 were determined to be 5.8±.6,1.8±.4 ,1.7±.4MHz/Torr (HWHM) at 275K respectively. The obtaining of these linewidth parameters is of considerable importance to the air pollution monitoring of NO_2 .
