Abstract
- Abstract: New rotational line strengths for the C2 Swan system ( ) have been calculated for vibrational bands with and , and J values up to J=34–96, using previous observations in 33 vibrational bands. Line positions from several sources were combined with the results from recent deperturbation studies of the and levels, and a weighted global least squares fit was performed. The updated molecular constants are reported. 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, combustion scientists and materials scientists who utilize C2 Swan spectra. Einstein A coefficients and f-values were also calculated for the vibrational bands of the Swan system. [Copyright &y& Elsevier]
