TL;DR: The fine-structure intervals in the ground 2 3P multiplet of lZC I have been measured with high accuracy by laser magnetic resonance as discussed by the authors, which has made possible the astronomical detection of far-infrared line emissions from I2C atoms in several interstellar sources.
Abstract: The fine-structure intervals in the ground 2 3P multiplet of lZC I have been measured with high accuracy by laser magnetic resonance. The results are: AR(3Y2-3P1) = 809.3446 (29) GHz and AE(3Y1-3Po) = 492.1623(7) GHz. These precise nieasurements have made possible the astronomical detection of far-infrared line emissions from I2C atoms in several interstellar sources, as reported in the accompanying Letter by Phillips et al.

TL;DR: In this article, the authors used laser magnetic resonance (LMR) for the study of pure rotational spectra of transient species in the gas phase, including atoms, ground states of molecules with up to 5 atoms, and most recently, metastable molecular electronic states in the millisecond lifetime range.
Abstract: Within the last few years, laser magnetic resonance (LMR) has emerged as a powerful technique for the study of pure rotational spectra of transient species in the gas phase. The sensitivity of this method is considerably higher than that of 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. Its domain of applicability presently includes atoms, ground states of molecules with up to 5 atoms, and most recently, metastable molecular electronic states in the millisecond lifetime range, and molecular ions. The only rigorous constraint on this applicability is that the species of interest must be paramagnetic.
