Calculation of spectroscopic constants and radiative parameters for the A 1I£ u + -X 1I£ g + and B 1I u -X 1I£ g + electronic transitions of the lithium dimer

Vibrational, rotational, and centrifugal spectroscopic constants; radiative parameters (the Einstein coefficients, oscillator strengths, and Franck-Condon factors); the wave numbers of rotational lines of electronic-vibrational-rotational transitions in the systems of bands A I-1 pound (u) (+) -X I-1 pound (g) (+) (0a parts per thousand currency signv'a parts per thousand currency sign20,0a parts per thousand currency signvaEuro(3)a parts per thousand currency sign37, j'=20,40) and B I-1 (u) -X I-1 pound (g) (+) (0a parts per thousand currency signv'a parts per thousand currency sign10,0a parts per thousand currency signvaEuro(3)a parts per thousand currency sign25, j'=0,20,40,50); and the radiative lifetimes for the vibrational-rotational energy levels of excited states of the lithium dimer are calculated. Calculations are carried out on the basis of semiempirical potential curves constructed in this work. The calculated energy parameters and radiative lifetimes are compared to the experimental data and the theoretical values available in the literature.
