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１５ Ｎ１６Ｏ 的Ｘ２ Π３／２ｖ ＝ 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．
LMR (Laser Magnetic Resonance) spectroscopy uses magnetic field scanning and magnetic field modulation to obtain paramagnetic molecular absorption lines with Voigt lines and different line widths. In this paper, a theoretical model of the linear model and experimental conditions are considered. A method to realize the precise simulation of LMR spectrum is proposed and the corresponding simulation calculation program is designed. X2 Π3 / 2v = 1 ← 0, Q2 (2.5) for 15 N16O at a laser frequency of 1842. The Zeeman transition spectrum at 8160 cm - 1 was simulated and the ideal simulation result was obtained. This method can be used as an effective aid to the identification of complex spectral analysis.
