Abstract: A new method is proposed in this paper, which is photoacoustics laser magnetic resonance (PALMR) in gas phase. PALMR spectrum of NO2 was observed for the first time in light intensity modulation and laser cavity freqnency modulation. The method has high sensitivity, especially, in low density and high pressure. Although the experiment was done in mid-infrared, this method may also be suitable for far-infrared.

Key words: Photoacoustics, LMR, PALMR
