Altitude distributions of the (0,0) 7619A band of O_2 atmospheric system (b^1Σ^+_g-X^3Σ^-_g) and of the (7,2) 6863A band of OH (X^2Π) in the night airglow emissions were measured at 31°N latitude. In spite of different seasons and local times of observations, all three measurements presented the peak emission rate occuring at an altitude of 94 ± 1 km for the O_2 band and at 90 ± 2 km for the OH band. The former emitting altitude is in basic agreement with the atomic oxygen density profile measured by the UV resonance fluorescence method, but the latter is considerably higher than expected from relevant theoretical models. After examining various possible causes for this discrepance, it is possible that the continuum airglow may contaminate our observations of the OH airglow. This may be aplicable also to other similar observations made so far in the near infrared.
