Far Infrared Laser Magnetic Resonance

Within the last few years, laser magnetic resonance (LMR) has emerged as a powerful technique for the detection of transient species in the gas phase and the study of their rotational spectra. The sensitivity of this method is con­ siderably higher than those of most competing techniques, such as conventional optical and microwave spectroscopy and gas-phase EPR, while the resolution attainable is comparable with that of the latter two methods. The domain of appli­ cability of LMR presently includes atoms, ground states of molecules with up to 5 atoms, and most recently, short lived
