Theoretical Study of the Rotational Structure of the c(4)'(1)sigma(u) (+) (6)-X-1 sigma(g) (+)(0-9) Absorption Bands of N-2

We have theoretically determined the absorption oscillator strengths and wavenumbers for rotationally resolved transitions of the c(4)'(1)sigma(u) (+) (6)-X-1 sigma(g) (+)(0-9) bands of N-2, which are relevant to analyze the spectra of planetary atmospheres. The Molecular Quantum Defect Orbital method has been used in our calculations. The interaction between the c(4)'(1)sigma(u) (+) (6) Rydberg state and the b '(1)sigma(u) (+) valence states has been considered using an adequate rovibronic energy matrix. In addition, we have calculated the lifetimes of the rotational levels of the c(4)'(1)sigma(u) (+) (6) state. We hope that the reported data, most of them for the first time, can be useful in the interpretation of planetary atmospheres where N-2 is present.
