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

摘要

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 delta(v,0)bands with v=2,3,the e(v,0)bands with v = 2,3,and the beta(v,0)bands with v= 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 delta(v,0)bands with v=0-3,the epsilon(v,0)bands with v=0-3,the beta(v,0)bands with v=6,7,9-12,14,and the gamma(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.
