Abstract: The quenching rate constants for the singlet states $(a')^{(1)}\Sigma_u^-$ ($v$ = 1–17), $a^{(1)}\Pi_g$ ($v$ = 0–14), and $w^{(1)}\Delta_u$ ($v$ = 0–13) of molecular nitrogen colliding with an N$_2$ molecule are calculated using quantum-chemical approximations. It is shown for the first time that both the intramolecular and intermolecular processes of electronic excitation transfer are significant for these states. Calculated rate constants are in satisfactory agreement with experimental data.
