The application of a vacuum-ultraviolet Fourier transform spectrometer and synchrotron-radiation source to measurements of bands of NO. VII. the final report

Abstract

Photoabsorption measurements of NO bands have been made by vacuum-ultraviolet Fourier transform spectrometry with a resolution of 0.12 cm-1 in the wavelength region of 166.2-196.2 nm. Accurate line positions are obtained for the δ (N,0) bands with N=2, 3, the ε (N,0) bands with N=2, 3, and the Β (N,0) bands with N=10, 12,14. Absolute term values are found for the corresponding upper levels C (2,3), D (2,3), and B (10,12,14). Accurate rotational line integrated cross sections have also been obtained for the lines in these bands. Integrated cross sections reported in our earlier papers [J. Chem. Phys. 109, 1751 (1998); 112, 2251 (2000); 115, 3719 (2001); 116, 155 (2002); 117, 10621 (2002); 119, 8373 (2003)] have been revised, and the results reported here comprise the δ (N,0) bands with N=0-3, the ε (N,0) bands with N=0-3, the Β (N,0) bands with N=6, 7,9-12,14, and the γ (3,0) band. For each band, the band oscillator strength is obtained from the sum of the line strengths of all rotational lines, and these are compared with other published values. © 2006 American Institute of Physics.
