A two-laser, pump-probe arrangement has been used to measure room-temperature rate constants for the collision-induced relaxation of NO(v ~ 2, 3) by O atoms. The rate constants ko(o) are equal to (2.2 + 0.2) × 10-~t and (2.5 + 0.3) x 10 -11 cm 3 s -1 for v = 2 and 3, respectively. These values are s

✦ Synopsis
A two-laser (IR overtone pump and UV laser-induced fluorescence probe) technique has been used to measure vibrational relaxation for NO(X *II, v= 3) colliding with NO, 02, and CH4 at 295 K. The total removal rate coefficients are: (3.26 k 0.24) X 10-'2cm3s-'forNO,(1.46f0.15)~10-'3cm3s-'for02,and(1.20+0.12)x10-'3cm3s-'forCH,.
