用激光诱导荧光技术研究了NO分子在激光激发到v=1时，与NO或其它分子（M=CO、N2、HCl、CO2和N2 O）碰撞时的振动弛豫，温度范围为300 ~ 600 K。对于NO-M系统，弛豫通过竞争性远共振V-V转移和V-T，R去激发过程发生。控制由激光激发的NO分子发射的荧光强度的时间衰减的速率常数的测量作为NO的摩尔分数的函数进行。从这些测量，以及先前在相同的NO-M系统上获得的那些，但是用激光激发的M分子，单独的值，即使在某些情况下是粗糙的，也可以推导出V-V转移和V-T，R去激发速率常数。除NO-N_2和NO-CO外，一个分子碰撞另一个分子的V-T，R去激发效率与该分子到另一个分子的V-V转移效率一样重要，甚至更大。
The vibrational relaxation of NO, laser‐excited to v=1, in collisions with NO or with other molecules, M=CO, N2, HCl, CO2, and N2O, has been studied by the laser‐induced fluorescence technique, in the temperature range from 300 to 600 K. For the NO–M systems, the relaxation occurs through competitive far‐from‐resonance V–V transfer and V–T,R deexcitation processes. Measurements of the rate constants governing the temporal decay of the fluorescence intensity emitted by the laser‐excited NO molecules were performed as a function of the molar fraction of NO. From these measurements, and those previously obtained on the same NO–M systems, but with the M molecules excited by laser, separate values, even if crude in some cases are deduced for the V–V transfer and V–T,R deexcitation rate constants. Except for NO–N2 and NO–CO, the efficiency of the V–T,R deexcitation of a molecule by collision on another one is shown to be as important as, or even greater than that of the V–V transfer from this molecule to the ot...
