It is shown that Orsini, et al. (1977) inference, from an analysis of Atmosphere Explorer data, that N2(+) ions in vibrationally excited states exhibit dissociative recombination coefficients in excess of 0.000001 cc/sec is incorrect. From the theory of the dissociative recombination process, an upper limit of 10 to the minus 7th power cc/sec is obtained for recombination by N2(+) ions in a particular vibration state at F-region electron temperatures. Available laboratory data on dissociative recombination of simple ions support this conclusion. As a possible alternative for the apparent rapid loss of vibrationally excited ions in the F-region it is suggested that the reaction N2(+) + O yields N + NO(+) may exhibit the necessary increase in reaction rate with vibrational excitation in the ions.
