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 allo wed subbands (2) Pi(1/2) - (2) Pi(1/2) and (2) Pi(3/2) - (2) Pi(3/2) o f the 2 <-- 0 vibrational band of the (NO)-N-14-O-16 molecule. These l ine parameters have been compared with previous experimental results a nd with the values available in the current HITRAN database. The measu red line intensities led to the determination of the transition dipole moment as well as the Herman-Wallis coefficients. Improved spectrosco pic constants were also obtained for the upsilon = 2 vibrational state . (C) 1997 Academic Press.
