Lambda-Splittings and Line Intensities in the First Overtone of Nitric Oxide
Using Fourier transform spectra, absolute line parameters (positions, Lambda splittings, and intensities) have been measured in the two allowed subbands 2Pi1/2-2Pi1/2 and 2Pi3/2-2Pi3/2 of the 2 <-- 0 vibrational band of the 14N16O molecule. These line parameters have been compared with previous experimental results and with the values available in the current HITRAN database. The measured line intensities led to the determination of the transition dipole moment as well as the Herman-Wallis coefficients. Improved spectroscopic constants were also obtained for the v = 2 vibrational state. Copyright 1997 Academic Press. Copyright 1997Academic Press
