Vibrational relaxation of NO/sup +/ (v) by collisions with NO, N/sub 2/, CO/sub 2/, CH/sub 4/, NO/sub 2/, He, Ar, and Kr has b een measured from thermal energy up to 1 eV. NO/sup +/ (v) is vibrationally relaxed at near the collision frequency by resonant charge transfer with NO. N/sub 2/ is quite efficient due to near resonant V ..-->.. V transfer. CO/sub 2/, CH/sub 4/, and NO/sub 2/ are efficient, Ar, Kr, and especially He are not. The quenching rate constants for N/sub 2/, CO/sub 2/, and CH/sub 4/ decrease with KE, those for NO and NO/sub 2/ do not.
