Line strengths and updated molecular constants for the C2 Swan system    [PDF]

James S. A. Brooke, Peter F. Bernath, Timothy W. Schmidt, George B. Bacskay
New rotational line strengths for the C2 Swan system have been calculated for vibrational bands with v'=0-10 and v"=0-9, and J values up to J=34-96, based on previous observations in 30 vibrational bands. Line positions from several sources were combined with the results from recent deperturbation studies of the v'=4 and v'=6 states, and a weighted global least squares fit was performed. We report the updated molecular constants. The line strengths are based on a recent ab initio calculation of the transition dipole moment function. A line list has been made available, including observed and calculated line positions, Einstein A coefficients and oscillator strengths (f-values). The line list will be useful for astronomers and combustion scientists who utilize C2 Swan spectra. Einstein A coefficients and f-values were also calculated for the vibrational bands of the Swan system.
