Abstract	The temperature dependences of the quenching rate constants of the states N2 ( ${\rm C} \ {^{3}{ \rm \Pi }_{u}}$ v′=0,1) by N2 (X) and of the state N2 ( ${\rm C} \ {^{3}{ \rm \Pi }_{u}} \ v^{\prime}=0$ ) by O2 (X) are studied. Time-resolved light emission from the gas was analyzed in the temperature range from 300 K to 210 K keeping the gas at constant density. In case of quenching by N2 (X), the quenching rate constant for the vibrational level v′= 0 increases by (13 ±3)% with gas cooling whereas the quenching rate constant for v′= 1 decreases by (5.0 ±2.5)% in this temperature range. For quenching by O2 (X), the quenching rate constant decreases by (3 ±2)% with gas cooling. The temperature variation of the N2 (C 3Πu v′=0) emission intensity for pure nitrogen and dry air are calculated using the obtained quenching rate constants and is compared with the experimental data available in the literature.
