Popis:	Removal rate coefficients for NO(B 2Π) in the v=2 and 3 levels are measured at 230 K for seven colliders: NO, N2O, CO2, O2, N2, Ar, and He. These measurements are the first below room temperature and are compared to earlier 295 K measurements. These NO(B 2Π) vibrational levels differ from each other in that the v=2 level is unperturbed, and the v=3 level is significantly perturbed by the v=12 level of the a 4Π state. Although there are large variations in removal rate coefficients between the two B 2Π vibrational levels, the effect of reducing the temperature on the removal rate coefficients is modest, the largest effects occurring with the least effective colliders, He and Ar.
