Abstract: The results are given of the calculations of populations of vibrational levels of $N_2(X^1\Sigma^+_g)$, $O_2(X^3\Sigma^-_g)$, and $NO(X^2\Pi)$ molecules in an air plasma whose parameters correspond to the positive column of a DC discharge at pressures of $30$$300 Pa and currents of 20$$110$ mA. Different processes are analyzed that form the distribution of molecules over levels, including the electron impact, $V$$V and V$$T$ exchange, chemical reactions, and heterogeneous deactivation. The calculation results for $N_2(X^1\Sigma^+_g)$ are compared with experiment. It is found that the values of the effective vibrational temperature characterizing the populations of $N_2(X^1\Sigma^+_g)$ are close to the values realized in a nitrogen plasma, and the difference of the vibrational temperatures of $O_2(X^3\Sigma^-_g)$ and $NO(X^2\Pi)$ from the gas temperatures is not significant, which is due to high frequencies of $V$$T$ relaxation of vibrational states of these molecules in collisions with $O(^3P)$ atoms.
