PRECISION EMISSION AND ABSORPTION-SPECTROSCOPY OF THE OXYGEN ATMOSPHERIC BANDS (B-(1)SIGMA(G)(-X-(3)SIGMA(G)(-)) FROM FOURIER-TRANSFORM SPECTROSCOPY())

The oxygen b(1) Sigma(g)(+)-X-3 Sigma(g)(-) electronic spectrum (the a tmospheric system) has been recorded at high resolution in both emissi on and absorption on the same Fourier transform spectrometer but with independent calibration methods used in each case. After correction fo r the known pressure shift of the transitions, excellent agreement is achieved between the data sets recorded in this work, allowing signifi cant errors to be identified within and between previous data sets. Mo lecular constants appropriate to the low pressure limit are determined from these new data for this important transition. (C) 1997 Academic Press.
