Collisional relaxation within the low-lying Rydberg states of NO has been investigated in NO/N/sub 2/ mixtures following the two-photon single vibronic level (SVL) excitation to C/sup 2/Pi(v' = 0,1), D/sup 2/..sigma../sup +/)v' = 0-3). The rate constants of energy transfer and electronic quenching by N/sub 2/ have been separately determined for C/sup 2/Pi(v' = 0,1) and D/sup 2/..sigma../sup +/(v' = 0,1). The 3psigma Rydberg state (D/sup 2/..sigma../sup +/) is found to be more stable than the 3p..pi.. Rydberg state (C/sup 2/Pi) for the collisions with N/sub 2/. Almost all of the metastable N/sub 2/A/sup 3/..sigma../sub u//sup +/ formed by the energy transfer are quenched by NO to generate NO A/sup 2/..sigma../sup +/(v' = 0,1) at a rate of (6.9 +/- 0.7) x 10/sup -11/ cm/sup 3/ molecule/sup -1/s/sup -1/. Other kinetic parameters are also reported in connection with the relaxation among these low-lying Rydberg states.
