Data Acquiring and Processing of the LMR Experiment

The Principle snd experimental Method of Laser Magnetic Resonance (LMR), the data acquiring and Processing technique and the feature of LMR spectra are briefly given in this Paper. The LMR system employed a 12 bits A/D boald, an AT/286 personal computer and an attached mulriplex amplifier which can obtain precise data than 12 bits.The flow chart of software and interface hardware are also shown in this paper. As an example, the nuclear magnetic hyperfine LMR spectra of NO at the laser frequency 1842.816cm^-1 is also demonstrated.
