摘要: LMR(Laser Magnetic Resonance)光谱技术采用磁场扫描及磁场调制获得顺磁分子吸收谱线,其谱线具有Voigt线型及各不相同的磁场线宽.本文考虑线型理论模型和实验条件,提出了一种实现LMR谱精密仿真的方法,并设计了相应仿真计算程序.对15N16O的X2Π3/2v=1←0,Q2(2.5)在激光频率为1842.8160cm-1处的塞曼跃迁谱进行了仿真,得到了理想的仿真效果.该方法可作为复杂光谱分析标识的有效辅助工具.

Abstract: Laser Magnetic Resonance(LMR) Spectroscopic technique employs sweeping magnetic field with ac magnetic flux as modulation to obtain spectra of free radicals. The spectral lines normally have Voigt line shape and different line width in field strength unit. This paper presents a universal simulation technique and program, which can be used to precisely simulate LMR spectra and any other spectra. Its application to the simulation of 15N 16O X2 Π3/2 v=1←0, Q2(2. 5) LMR spectra proved its success and high accuracy. Remarkable agreement between the experimental spectra and the synthesized spectra confirms that it will be a useful computer aid to the analysis of complex spectra.
