摘要：
Theoretical absorption oscillator strengths for rotational lines of the c(4)'(1)Sigma(+)(u)(4)-X-1 Sigma(+)(g)(0-7) bands of N-2, which are relevant to analyze the spectra of the atmospheres of the Earth, Titan, and Mars, are reported. The known interaction between the c(4)'(1)Sigma u(+)(4) and c(3)(1)Pi(+)(u)(4) Rydberg states and the b'(1)Sigma(+)(u)(13) valence state has been dealt with through an appropriate rovibronic energy matrix. Deviations in the intensity distribution of the rotational lines from considerations based on Honl-London factors have been found for each of the studied bands. Emission branching ratios for the above bands and lifetimes of the rotational levels of the v = 4 level of the c(4)'(1)Sigma(+)(u) state are also reported.
