Contributions of intermolecular electron energy transfers in the electronic quenching are calculated for molecular collisions N<sub>2</sub>(A<sup>3</sup>&Sigma;<sub><I>u</I></sub><sup>+</sup>, W<sup>3</sup>&Delta;<sub><I>u</I></sub>)+N<sub>2</sub>(X<sup>1</sup>&Sigma;<sub><I>g</I></sub><sup>+</sup>, <I>v</I>=0), N<sub>2</sub>(A<sup>3</sup>&Sigma;<sub><I>u</I></sub><sup>+</sup>)+N<sub>2</sub>(X<sup>1</sup>&Sigma;<sub><I>g</I></sub><sup>+</sup>, <I>v</I>&ge;0), N<sub>2</sub>(A<sup>3</sup>&Sigma;<sub><I>u</I></sub><sup>+</sup>)+O<sub>2</sub>(X<sup>3</sup>&Sigma;<sub><I>g</I></sub><sup>&minus;</sup>, <I>v</I>=0&ndash;2), O<sub>2</sub>(a<sup>1</sup>&Delta;<sub><I>g</I></sub>, <I>b</I><sup>1</sup>&Sigma;<sub><I>g</I></sub><sup>+</sup>)+O<sub>2</sub>(X<sup>3</sup>&Sigma;<sub><I>g</I></sub><sup>&minus;</sup>, <I>v</I>=0&ndash;2). The calculation has allowed one to estimate the product branching ratios. It is shown that there is a dependence of the calculated rate coefficients on the vibrational excitation of N<sub>2</sub>(X<sup>1</sup>&Sigma;<sub><I>g</I></sub><sup>+</sup>) and O<sub>2</sub>(X<sup>3</sup>&Sigma;<sub><I>g</I></sub><sup>&minus;</sup>) molecules. In many cases, the calculated rate coefficients have a good agreement with available experimental data.
