The quenching of vibrationally excited N+2 ions by various neutrals

Using a selected ion flow tube, the quenching of the vibrational excitation of N+2 (X, v not = 0) by Ne, N2, NO, and CO2 was investigated, and the following thermal quenching rate coefficients, k /sub q/, were obtained respectively (all in units of 10-10 cm3 sec-1): 0.045, 5, 1.2, ≤ 0.3, ≤ 1. For the charge transfer of N+2 with O2, NO, and CO2, the respective rate coefficients (in units of 10-10 cm3 sec-1) 0.5, 3, and 7 were obtained independently of whether N+2 (X) was vibrationally excited or not
