Magnetic dipole rotation spectrum of oxygen

Abstract

The identification of the magnetic dipole rotation spectrum of oxygen in atmospheric studies has been confirmed by laboratory measurements in the spectral range 12 to 65 cm -1 , using interferometric techniques combined with long absorption paths and pressures of 2 to 3 atmospheres. A quantitative comparison has also been made between the laboratory observations and the theoretical predictions, giving agreement in the frequencies to within +0∙026 cm -1 and that of the integrated line-strengths within experimental error, as defined by the signal/noise ratio of the observed spectra.
